Great Parchment Book goes to Glasgow (and Finland)

Posted on

edcr2016-2We were fortunate that the launch of the major academic paper on the Great Parchment Book project coincided with London Metropolitan Archives’ Charlie Turpie presenting the project at the Symposium on Evaluating Digital Cultural Resources (EDCR2016) in Glasgow on 13 December 2016.

Charlie commented afterwards that one of the themes that emerged from the symposium was that physical and digital often go hand in hand and continue to have a relationship – this came out in various papers. The Great Parchment Book presentation captured that perfectly – seeing the transformation from shrivelled parchment to digital image was a real wow for the audience. The audience also got the pathos of the membranes being preserved for 200 years just in case they could be made accessible one day.A box of folios from the Great Parchment Book before they were conserved and repackaged

One attendee was very pleased that the Great Parchment Book website features both the before and after shots of the folios as other projects only show the digitally enhanced images which is not as useful as having both.

That the presentation was very well received is reflected in the contemporaneous comments on Twitter of which a selection is given below:

  • Fantastic #GreatParchmentBook project presented by @CharlieTurpie @LdnMetArchives #EDCR2016 Loved the poppadoms analogy!
  • Gasp from audience as @CharlieTurpie shows an image of the #greatparchmentbook fragments in a box. Yikes! #edcr2016
  • ‘a mass of scorched and dirty fragments’ – tricky task to create a digitised version of the #greatparchmentbook #EDCR2016
  • Project allows users to navigate and flatten digital images to digitally uncover the text within. Cool! #greatparchmentbook #edcr2016
  • Digital reconstruction to enable access is fab; book & its contents are also significant for local community #edcr2016 #greatparchmentbook
  • Definitive article on fascinating #greatparchmentbook released today! Can’t wait to read more on it after #EDCR2016
  • #greatparchmentbook is such an awesome project!

You can catch up with the Great Parchment Book project on Twitter by using the hashtag #greatparchmentbook.

The paper, published in Oxford University Press’s Digital Scholarship in the Humanities journal, is freely available online. At the time of writing it is doing very well online and is already in the top 5% of papers in Altmetric (which tracks online research outputs), and 99th centile for attention; it is the number one output from digital scholarship in the humanities.

The Great Parchment Book’s world tour continued with Tim Weyrich, Professor of Visual Computing, Virtual Environments and Computer Graphics Group, Department of Computer Science, University College London, lead of the project digital acquisition and reconstruction, giving the keynote at SyysGraph 2016, the Finnish computer graphics scene’s leading annual event, the previous evening. His talk on Problem-Aware Digitization of Cultural Heritage Artifacts featured the Great Parchment Book as one of the case studies and he was able to promote the paper which was published the following day.

Great Parchment Book: major paper published

Posted on

EssenceOur partners at UCL have announced the publication of a major paper describing the process of conserving, imaging, virtually flattening, and finally reading the Great Parchment Book of the Honourable The Irish Society, held in London Metropolitan Archives. As followers of this blog will know the project saw archivists, conservators, imaging scientists, historians, computer scientists, and digital humanities experts working together in an interdisciplinary, international partnership. We developed a low-cost process for conserving, digitizing, 3D-reconstructing, and virtually flattening the fire-damaged, buckled parchment, enabling new readings and understanding of the text to be created.

GlobalThe paper, published in Oxford University Press’s Digital Scholarship in the Humanities journal, presents a complete overview of the project, detailing the conservation, digital acquisition, and digital reconstruction methods used. It is freely available in open access, meaning anyone can read the details of the project, and see our images and videos to understand the scope and scale of the project, and its contribution to the restoration of the Great Parchment Book. It is freely available online.

Note: Please use the hashtag #greatparchmentbook when referring to the project on social media.

Significance of the project for some of the key partners

ucl-veivProfessor Tim Weyrich, Professor of Visual Computing, Virtual Environments and Computer Graphics Group, Department of Computer Science, University College London, lead of the digital acquisition and reconstruction said: “I feel privileged having been able to conduct computer science and imaging research in the context of a project of such cultural importance. We were fortunate enough that the engagement with the humanities’ unique problem domain allowed us to go beyond mere application of known techniques, pushing the boundary in our own research field while making a tangible difference to the wider public.”

irish-society-coat-of-arms-colour-jpgEdward Montgomery, Secretary of The Honourable The Irish Society, said: “We are delighted that The Honourable The Irish Society has been part of a major collaborative project to bring The Great Parchment Book, one of its most historic documents, ‘back to life’. The Book is a marvellous testament to history and provides a detailed account from 1639 of the City of London’s role in the Plantation of Ulster and its administration. It is a valuable tool for anyone interested in their ancestral history within Ulster and an excellent teaching aid for those exploring early modern Ireland.”

lma-logoGeoff Pick, Director of London Metropolitan Archives said: “The City of London Corporation, through London Metropolitan Archives, has been delighted to be a major partner in the Great Parchment Book project, one of the most innovative in the archive sector in recent years.  It places great value on the Book, not least in helping the City’s support for the 400th anniversary of the building of Derry’s city walls in 2013 and the state visit to London of the President of Ireland in 2014.   The Book has also been recognised by UNESCO as being of outstanding national importance this year when it was inscribed on the UK Memory of the World Register, the first on the Register concerning Northern Ireland.”

UCLDH logoProfessor Melissa Terras, Director of UCL Centre for Digital Humanities said: “It has been a pleasure to work on this project, which has brought together expertise from so many different angles, allowing us to finally provide advanced access to this important, but very damaged, document. The conservation, imaging, and reconstruction have all contributed to the creation of a digital resource of lasting value for researchers, students, and the wider public. Our work encourages further understanding of the role of the City of London in the plantation, and the importance of the Great Parchment Book to its local, national, and international contexts. It also shows us the benefits of undertaking advanced digital projects in the area of cultural heritage.”

An essential and enduring online resource

Posted on

The Great Parchment Book website is proving to be an essential online resource in several fields of study, with even the blog itself used as a case study.

Examples which have come to our attention recently include:

 

If text then code websiteThe Great Parchment Book project is being used as a case study in an undergraduate course in the Digital Humanities. If text then code is taught by Dr Diane Jakacki at Bucknell University, a liberal arts college in Lewisburg, Pennsylvania in the United States of America. On the course students write and critique code as a form of textual engagement, and amongst other skills, gain competency with TEI­-compliant XML, the code we used to encode the text of the Great Parchment Book and facilitate online accessibility. Currently, London Metropolitan Archives, in partnership with UCL, are looking at how we can make the XML from the Great Parchment Book more widely available.

 

1641 depositions learning websiteThe Great Parchment Book is referenced as an enriching research resource for understanding the history of the Ulster Plantation on Trinity College Library Dublin’s learning website about the 1641 Depositions. The digitisation of the depositions, which we have looked at previously on the Great Parchment Book blog, has opened up these sources for use in the classroom and 1641 Depositions Bridge21 Learning Resources website enables secondary school students in Ireland to hone their skills as young historians while learning about the plantations, the 1641 rebellion and their impact on Irish history.

 

NMCT case studiesThe National Manuscript Conservation Trust, to which we are grateful for funding the Great Parchment Book conservation project, features it as a case study on its website and also highlights the blog as one of the best about conservation projects that have benefitted from NMCT grants.

 

Cilip blogThe Chartered Institute of Library and Information Professionals (CILIP) also asked London Metropolitan Archives to write about the pleasures and pitfalls of writing the Great Parchment Book blog for their own blog as a case study.

 

 

Inside HistoryAustralia and New Zealand’s Inside History Magazine has included a link to the Great Parchment Book website in its latest issue as a handy hint for those searching for Northern Ireland ancestors, especially those from the County of Londonderry. This has been driving a lot of traffic to the website since it was published, and some of those visitors are then going on to look at other related Irish genealogical sources for which we provide information and links.

 

Sometimes we are frustrated as we can’t see exactly what the Great Parchment Book website is being used for. For example, we know it’s  referenced in an online learning module run by the University of Haifa in Israel, but we can’t see what it is as it’s for registered users only!

 

UCLThe Great Parchment Book website is used cross-discipline and worldwide, reflecting the comprehensive and enduring nature of the work it represents. Not least, the Great Parchment Book is used by our close partners at UCL in the Centre for Digital Humanities and Department of Computer Science and you can follow this on UCL’s own website relating to the project and on related pages.

Continuing the stories of the Great Parchment Book: Irish genealogy online

Posted on

There are an estimated 70 million people worldwide claiming Irish ancestry and we are very pleased that the Great Parchment Book project is now accessible and available online to all those who wish to trace their Irish roots.

To continue the story of those recorded in the Great Parchment Book, the genealogical collections of Derry City and Strabane Archive & Genealogy service offer another significant resource. These include a database of over one million records including traditional family history records such as birth, marriage and death records.

rootsireland.ie Derry GenealogyThe Archive & Genealogy service is currently in partnership with Irish Family History Foundation to offer a Genealogy  service.  The database of over one million records, dating from 1642 to 1922, created between 1982 and 2007 as a project of the Inner City Trust, from the major civil and church registers of the city and county of Derry~Londonderry and Inishowen, County Donegal is now available at www.derry.rootsireland.ie.

The Derry City and Strabane Archive & Genealogy service is responsible for the preservation, interpretation and creation of access to the civic records of the Council and its predecessor, the Londonderry Corporation.

DerryStrabane ArchiveGenealogy ServiceThe extensive archive collection constitutes an extremely valuable source of information both for the history of the City and the Council and provides a comprehensive record of the city’s development from the latter half of the 17th century to the present day. It consists of minute books, legal documents, architectural drawings and plans, and private collections. The material ranges from business collections, and items relating to industry, shirt factories, railways, political movements and social history. The genealogical collections includes a database of over one million records including traditional family history records such as birth, marriage and death records.

Some of the records of the Londonderry Corporation have been digitised and are available online in association with the Public Record Office of Northern Ireland (PRONI) specifically:

The Londonderry Corporation minute books from 1673. In the late 17th and 18th centuries, the city’s business life consisted of merchants and craftsmen such as butchers and bakers, tailors and shoemakers, smiths and saddlers, joiners and coopers.

Records of the Freemen of the City of Londonderry from 1675. In the 17th and 18th centuries, only Freemen of the City were entitled to conduct business, own property and receive protection within the walled city.

These records continue the stories of the inhabitants of Londonderry started in the Great Parchment Book.

Studying digital humanities in London

Posted on

In London we are fortunate to have two leading centres for the study of digital humanities, the UCL Centre for Digital Humanities and King’s College London Department of Digital Humanities. The Great Parchment Book project and follow-on research is very closely allied to the former, but we also have had links to the latter.

UCLDH logoDigital Humanities research takes place at the intersection of computational technologies and humanities and is a relatively new field of research and teaching. It is highly collaborative and typically works across a wide range of disciplines, involving different institutions, both nationally and internationally. It has a crucial role to play in developing the use of advanced technology in the arts and humanities, making possible new kinds of research which positively impact on cultural heritage and memory institutions, libraries, archives and digital culture.

King's College LondonBoth UCLDH and King’s College Department of Digital Humanities offer MAs in Digital Humanities for which applications are currently open. Both have also produced very accessible videos which explain more about Digital Humanities research and study and are well worth viewing. Find out more via the links below:

1615-1745: post-digital issues and concerns

Posted on

Previously on the Great Parchment Book blog we have looked at related sources such as the 1641 Depositions held at Trinity College Library Dublin.

1641 DepositionsThe 1641 Depositions comprise transcripts and images of all 8,000 depositions, examinations and associated materials in which Protestant men and women of all classes told of their experiences following the outbreak of the rebellion by the Catholic Irish in October, 1641. The 1641 Depositions Project had similar aims to the Great Parchment Book project to conserve, digitise, transcribe and make the depositions available online in a fully TEI (Text Encoding Initiative) compliant format.

You can hear more about the project and it’s future at the forthcoming CERL Dublin Manuscripts Conference 25-27 May 2016 being held in the Library of Trinity College where Professor Jane Ohlmeyer, one of the Principal Investigators on the project, is speaking on ‘The 1641 Depositions: what now?’ in a session on ‘Post-digital issues and concerns 1615-1745’.

cerl-logoThe conference is entitled ‘Unique and universal: challenges for the manuscript librarian’ and is the 7th conference of the European Manuscript Librarians Expert Group of CERL (the Consortium of European research Libraries).

The primary aims of the Group are to act as a forum for curatorial concerns, and to enhance understanding and practical cooperation among curators across Europe. The conference will focus on the themes of commemorations and anniversaries, materiality, and post-digital issues and concerns.

Great Parchment Book retrospective: the legacy and the future

Posted on

With the successful outcome of the Great Parchment Book project well-established and in the public eye once again, we’ve been reflecting back on the different elements which made up the project and trying to make sense of the journey.

Over the past few weeks we have looked at conservation, digital imaging, transcription and textual encoding, historical importance and synergy with other sources, outreach and public recognition. To round up, we’re going to look at legacy and the future.

Great Parchment Book foliosThe conservation, digital reconstruction and resulting transcription of the Great Parchment Book have provided a lasting resource for historians researching the Plantation of Ulster in local, national and international contexts.

A schools programmes associated with the exhibition is underway in Derry. The Great Parchment Book is also being used in undergraduate teaching at the University of Ulster and is proving to be a vital resource for postgraduate and post-doctoral research. The website and project blog are also used extensively by students of conservation and digital humanities.

After

On the digital imaging side, UCL has enabled free access to the digital reconstruction process through a stand-alone version of the software (available on the UCL project page). The open-sourcing of UCL’s platform should enable other institutions to access the acquisition and restoration process themselves. Meanwhile LMA wants to explore the possibility of developing our role as a centre of expertise for the conservation, imaging, and digital restoration of distorted parchments and other damaged material, working in tandem with UCL to maintain the trajectory we have built up working on this together.

LMA is continuing to post updates on the project on the blog making connections with other digital projects and technologies revolutionising access to archives and cultural artefacts, and exploring the synergies with other documents relevant to the story that the Great Parchment Book has to tell. Watch this space!

Great Parchment Book retrospective: public recognition

Posted on

The successful outcome of the Great Parchment Book project is now well-established and the project has been very much in the public eye. This post, in our occasional retrospective, is about public recognition.

The project was an ambitious collaborative undertaking and each element was a major piece of work in its own right and different funders were approached for each aspect of the project:

  • The Engineering and Physical Sciences Research Council funded a four year Engineering Doctorate in the Virtual Environments, Imaging and Visualisation programme at University College London for the digital imaging and virtual reconstruction of the Great Parchment Book from September 2010.
  • The National Manuscripts Conservation Trust awarded a grant for conservation in 2011.
  • The Marc Fitch Foundation, the Irish Society and several of the Great Twelve City of London livery companies (Clothworkers’ Company, Drapers’ Company, Fishmongers’ Company, Goldsmiths’ Company, Ironmongers’ Company, Mercers’ Company, Merchant Taylors’ Company and Skinners’ Company) gave grants towards the transcription and textual encoding of the document and its online publication in 2012.
  • Advice and support was given by Professor James Stevens Curl, The British Library, The National Archives and The Trustees of Lambeth Palace Library.
  • Derry City Council Heritage and Museums Service, LMA and UCL also provided funding and staff time and resources.

Great Parchemtn Book public recognition and awards

The Great Parchment Book project has been nominated for a number of awards, evidence both of the importance of the document and the strength of the project.

Finally, the importance of the Great Parchment Book project has been recognised at the highest level. First Minister of Northern Ireland, the Rt Hon Peter D Robinson MLA, wrote in 2013 that “I cannot praise the work of the LMA & UCL highly enough. In completing this mammoth project they have succeeded in opening a veritable treasure trove of information relating to a most significant period in the history of Ulster; and illustrating as never before the central role played by the London Guilds in the creation and preservation of the city of Londonderry and its environs.”

President of Ireland

Also in 2013, the Lord Lieutenant of the city of Derry, Sir Donal Keegan, was shown a folio relating to the city when he was presented with the Freedom of the City of London. During his visit to the United Kingdom in 2014, the President of Ireland, Michael D Higgins, viewed a display of folios from the Great Parchment Book at a State Banquet in his honour at Guildhall.

Great Parchment Book retrospective: outreach

Posted on

The Great Parchment Book had been inaccessible to researchers for over 200 years owing to its fragile state. Our overriding objective with the project was to make the manuscript available again to as wide a range of people as possible, not just for the benefit of scholars and other researchers, but also for the communities to which it was most relevant. In our occasional series of posts looking back at the project, we turn our attention to engagement and outreach.

The original ambition was to produce a digitally reconstructed and fully accessible manuscript that could take pride of place in the exhibition in Derry Guildhall opening in June 2013 to commemorate the 400th anniversary of the building of the city walls during Derry’s year as UK City of Culture.

Overall, the project was more successful than we could have hoped. The Great Parchment Book website went live on 30 May 2013 on the eve of the opening of the Derry Guildhall exhibition; it features a blog and an embedded video. Since its launch it has attracted 87,000 page views to date and counting, and has been a great success with a whole range of people around the world including academic researchers, local and family historians, conservators and those interested in the digital humanities.

The exhibition curated by Derry City Council Heritage and Museums Service entitled Plantation: People, Process, Perspectives opened in Derry’s Guildhall in June 2013. The exhibition had nearly 270,000 visitors in its first year and has had over 864,000 visitors to the end of 2015 including school groups. Such has been its popularity that it is set to continue for the foreseeable future. Visitor feedback has been very positive, including high praise for the original archive material which for the first ten months included an original folio of the Great Parchment Book and other documents from the Irish Society archives.

Great Parchment Book Day 2014

All aspects of the project have been celebrated and presented by LMA and University College London at various conferences and events including the Archives and Records Association Conference, Brighton 2012; Digital Humanities Conference, Nebraska USA 2013; Plantation Families event, Belfast/Derry, 27-28 September 2013; Opposites Attract: Science and Archives, LMA 21 March 2014; STEM from the City careers day, City of London Guildhall 27 June 2014; Great Parchment Book Day, LMA 25 July 2014; International Council on Archives annual conference, Girona, Spain 15 October 2014; University of Melbourne, Australia 31 October 2014; ARA Conservation Training Committee and Instructors, LMA 20 November 2014; Association for Historical and Fine Art Photography’s annual conferences, London 27 November 2014 and 22 October 2015.

The project has been published in a range of publications (the UCL project page has a list of the most significant and provides access to the free software produced in the course of the project) and is featured on many websites including the European History Primary Sources (EHPS) website and that of the International Council on Archives and the National Manuscripts Conservation Trust. The Great Parchment Book project has featured in an article in the Observer, 5 July 2015 on conservation technology.

It is used in teaching history at all levels especially in Northern Ireland, as well as for teaching students of conservation and digital humanities around the world.

Great Parchment Book retrospective: imaging

Posted on

In our previous post in this occasional series reflecting on the different elements which make up the Great Parchment Book project we looked at conservation; now it’s the turn of digital imaging.

It had been evident for many years that traditional conservation alone would not produce sufficient results to make the Great Parchment Book accessible, although there had been at least one attempt in the past. Following discussions with conservation and imaging experts, it was decided to flatten the parchment sheets as far as possible appropriate to their fragile state to enable digital imaging with the ultimate aim of reconstructing the manuscript digitally. We knew from the first that this was an undertaking without a certain result as we were committed to exploring new techniques and technologies; nothing else had any chance of success.

A partnership with UCL established a four year Engineering Doctorate in the Virtual Environments, Imaging and Visualisation programme in September 2010 (jointly funded by the Engineering and Physical Sciences Research Council and LMA) with the intention of developing software that would make the distorted text legible. The doctoral student, Kazim Pal, was supervised by Melissa Terras, Director of the UCL Centre for Digital Humanities and Professor of Digital Humanities in the Department of Information Studies at University College London and Tim Weyrich, Professor of Visual Computing in the Virtual Environments and Computer Graphics group in the Department of Computer Science, University College London and Deputy Director of the UCL Centre for Digital Humanities.

During the digitisation phase, which in part ran alongside the conservation, a set of images was captured for each page and used to generate 3D models. Ground-breaking software was developed to allow these models to be flattened and browsed virtually.

digitally flattened parchmentKazim’s work was more successful than we could have hoped with the digitally flattened images of the folios featuring on the dedicated Great Parchment Book website alongside a transcript making the Great Parchment Book available for consultation by researchers once more.

The digitisation of the Great Parchment Book was recognised in 2014 when the project received a European Succeed Award (for digitisation focussing on textual content) Commendation of Merit.

You can explore the digital imaging of the Great Parchment Book in detail on the blog (go to the end of the page once you’ve clicked the link to read in chronological order).

See also the UCL project web page which includes access to the free software produced in the course of the project and the amazing video of the flattening software in action.

We also continue to highlight other developments which are revolutionising access to archives through the use of new technology and innovation on the blog.

When we embarked on the Great Parchment Book project, we were very uncertain that we would be able to achieve our aim: a digitally reconstructed and fully accessible manuscript that could take pride of place in the exhibition in Derry Guildhall opening in June 2013 to commemorate the 400th anniversary of the building of the city walls.

Great Parchment Book partners

The project was an ambitious collaborative undertaking committed to exploring new techniques and technologies; nothing else had any chance of success. Each element was a major piece of work in its own right and different partners and funders were approached for each aspect of the project.

Now with the successful outcome well-established and the project in the public eye once again, it seems a good time to reflect on the different elements which made up the project and look back on the journey.

3D imaging in cultural heritage

Posted on

Interdisciplinary research has been key to the success of the Great Parchment Book project. In the next seminar in the UCLDH seminar series, Mona Hess, Research Manager at 3DIMPact (3D Imaging, Metrology & Photogrammetry), UCL Civil, Environmental and Geomatic Engineering, offers a cross-disciplinary approach for 3D imaging metrology and 3D printing in cultural heritage, arts and humanities and for creative industries.

The potential of 3D images is increasingly recognized by heritage professionals for opening up new technological possibilities for digital documentation, analysis and research, exhibition display and education. Currently there is no comprehensive understanding of the 3D image qualities for a digital artefact from the point of view of a heritage professional.  In this talk, Mona Hess will give an overview of the qualitative research undertaken to explore heritage professionals’ requirements, and examine the outcomes of the research, including a framework to assess 3D image quality and to plan 3D imaging projects according to user requirements and sensor capabilities.

X-ray technology reveals a hidden library

Posted on

The Great Parchment Book project through interdisciplinary research has allowed researchers to digitally explore the contents of a badly damaged and distorted manuscript. Recently, we’ve come across another collaborative project which has allowed researchers to digitally leaf through invisible pages and gain access to a hidden library.

Early-modern books contain hidden treasure: fragments cut from medieval manuscripts placed inside bindings to reinforce the textblock and to provide support for the binding. In his blog Medieval Books, Dr Erik Kwakkel from the University of Leiden in the Netherlands looks at how to gain access to the fragments using the Macro X-ray Fluorescence Spectrometry (MA-XRF) technology developed by Joris Dik and his team at Delft University in collaboration with industrial, academic and museum partners.

The blog post – X-Rays Expose a Hidden Medieval Library – gives an exclusive look behind-the-scenes at the process, and discusses the challenges and opportunities it presents for the future.

Multispectral imaging of parchment documents and much more

Posted on

LMA is pleased to be working with UCL on research into the multispectral imaging of archival documents. Find out more here about recent research on degraded historical texts written on parchment, and events and discussions about this hot topic.

Multispectral imaging of degraded historical texts written on parchment

LMA is pleased to have contributed the raw material which allowed our partners at University College London to carry out research on the multispectral imaging of degraded historical texts written on parchment. They chose to focus on parchment documents for their study, given that parchment remains the primary medium of large quantities of culturally important documents in archives, museums, libraries, and private collections.

Multispectral imaging is an advanced digitisation method for acquiring image data over a series of wavelengths across the light spectrum. Combined with image processing, it has become a valuable tool for the enhancement and recovery of information contained within culturally important documents, providing a means, in some cases, to recover lost text, or examine other features no longer detectable by the human eye. The aim of the research was evaluate this technique in a structured fashion, to provide recommendations on how best to capture and process images when working with damaged and abraded textual material.

“The value of critical destruction: Evaluating multispectral image processing methods for the analysis of primary historical texts” by Alejandro Giacometti, Alberto Campagnolo, Lindsay MacDonald, Simon Mahony, Stuart Robson, Tim Weyrich, Melissa Terras, Adam Gibson was published in the online journal Digital Scholarship in the Humanities by Oxford University Press on behalf of European Association for Digital Humanities on 7 October 2015.

More than the eye can see: Digital Humanities spectral imaging

Effective spectral imaging requires not just collection of quality images, but the ability to manage and exploit large amounts of integrated data and metadata for cultural heritage studies. Mike Toth, Honorary Research Associate at UCL, who is supporting the integration of spectral imaging systems into digital humanities studies and institutions, is speaking about this at a seminar “More than the eye can see: Digital Humanities spectral imaging” at UCL on 28 October 2015 5.30-6.30pm.

All welcome and there will be drinks and discussion after the talk, but please note that registration is required. More information is available here.

Sightlines

Mike Toth was also speaking in the United States at Sightlines, a panel discussion and technology petting zoo with light-based technologies, presented by the Digital Futures Consortium of Harvard University on 14 October 2015. This event brought together experts and thinkers from multiple disciplines to discuss 2D, 3D, and multispectral imaging for cultural heritage collections and is one of a three part series. The presentations will be published on the Sightlines website in due course.

Great Parchment Book project in The Observer

Posted on

The Great Parchment Book project has featured in an article in The Observer, 5 July 2015 on conservation technology.

The Observer interviewed project lead Philippa Smith and conservation project supervisor Caroline De Stefani at LMA, and Professor Melissa Terras, co-supervisor with Dr Tim Weyrich, of the Great Parchment Book project at UCL.

The project is the meat in the sandwich between discussion of the British Library’s work on preserving old newspapers and project partner UCL’s research into multispectral imaging.

LMA is continuing to work with the Centre for Digital Humanities at UCL and also with the British Library through a SEAHA fully-funded studentship on the Multispectral Imaging of Documentary Material as reported in an earlier Blog post.

We’ll be updating this Blog with news of the SEAHA Multispectral Imaging project in due course, but watch this space for some exciting news about the Great Parchment Book project coming soon!

 

Supporting personal scholarship

Visit to see multispectral imaging set up at UCL

Posted on

Interesting visit this morning (Tuesday 28 April 2015) to see the Multispectral Imaging System in the UCL Centre for Digital Humanities Multimodal Digitisation Suite. Meghan Hill, a hyperspectral imaging technician, gave an insightful demonstration using examples from the Library of Congress in the USA, as well as showing the live set up. The system gives UCL world-leading capabilities in the advanced imaging of cultural and heritage material and London Metropolitan Archives is pleased to be associated with UCLDH in this important research.

UCLDH multispectral digitisation

The visit has already given us some ideas about archives held by LMA to which the non-invasive techniques shown us can be applied to help us better understand the documents physically and make the information they contain more accessible, and indeed even reveal hidden treasures. Watch this space!

Research opportunity in the digital humanities

The Digital Atlas of Derry~Londonderry

Posted on

A digital mapping resource is being developed which allows the user to compare maps of Londonderry for different time periods. It includes Thomas Raven’s map of 1622 which was surveyed just prior to the compilation of the Great Parchment Book.

The Digital Atlas of Derry~Londonderry is a collaboration between the Royal Irish Academy, Derry City Council and The School of Geography, Archaeology & Palaeoecology at Queen’s University Belfast.

Based on the Irish Historic Towns Atlas, no. 15, Derry~Londonderry by Avril Thomas (Royal Irish Academy, Dublin, 2005), the Digital Atlas provides users with historical and topographical information about the city of Derry for selected time-periods. The key map is a reconstruction of the city in 1831, which is presented in an interactive way. Streets, buildings, city walls/gates and public buildings are mapped and further detail such as name, dates and other historical information is provided in pop-up boxes.

Digital map of Derry-Londonderry

As well as the 1831 map, earlier and later historical maps, including Raven’s 1622 map, can be overlaid and compared. The different map layers reveal not only the way the city developed, but also the way that mapping evolved since the walled city was founded in the 17th century.

This web-GIS resource is still at an experimental stage, but is worth taking a look at.

Digital humanities in a new timeframe

Posted on

As we near the end of 2014 and reflect on what we have achieved in the past year and what we hope to achieve in 2015,  I encourage you to read “Digital Humanities in the Anthropocene”, a talk by Bethany Nowviskie delivered at the Digital Humanities 2014 conference in Lausanne, Switzerland. 

Of course Bethany mentions the Great Parchment Book, “a brittle wad since the Guildhall fire over two centuries ago, and now unfolded virtually and legible again”, in the context of successes with “the digital recovery of texts, objects, and traces of human experience thought long since lost to time. Here (from the outside, at least), DH accomplishments look magical.”

This thought provoking piece on the place of technology and the humanities in the world as it is now and will be in the future, has provoked a wide-ranging discussion which you can follow from the links in Bethany’s blog.

And if you want to catch-up more generally with what happened at the the Digital Humanities 2014 conference, details – including videos of many of the talks – are posted on the DH2014 website. Professor Melissa Terras from UCL who was Programme Committee chair delivers Bethany’s talk which was the Community Plenary lecture.

A look at the future of digitisation

Posted on

The Association for Historical and Fine Art Photography for cultural heritage imaging professionals in the UK and Ireland, held its 2014 annual conference on 27 November at the Wellcome Trust in London. The theme of this year’s conference was ‘Best practice?’ and focussed on managing change in a world where technology is continually improving digital photography.

The Keynote speaker was Cecile van der Harten, Head of the Imaging Department at the Rijksmuseum in the Netherlands whose talk was entitled ‘2+3D Photography – practice and prophecies – A look at the future of digitisation’.

She was followed by wide range of other speakers including Dr Tim Weyrich of University College London, who showcased the work of UCL including the Great Parchment Book project.

Abstracts of the all the talks can be found here and the view from the floor can be explored via the Twitter hashtag #ahfap14.

Cecile also looked forward to an international conference ‘2+3D Photography – Practice and Prophecies’ at the Rijksmuseum, 15–16 April 2015. As well as promoting the adoption of existing standardized workflows and exploring new digital challenges, the conference will also look at how new techniques can be incoporated into international standards of practice.

Great Parchment Book in Australia

Posted on

Professor Melissa Terras, Director of the UCL Centre for Digital Humanities and Great Parchment Book project partner has been visiting Australia and was one of the featured speakers at eResearch Australasia 2014. She also gave a talk about the Great Parchment Book project at The University of Melbourne on 31 October.

Her lecture at eResearch Australasia 2014 – entitled Across the Humanities and Science Divide: Advanced Digital Projects in Cultural Heritage – examined the ever increasing need for the development and appropriation of advanced computational methods within the Humanities and Cultural Heritage. Although the Arts, Humanities and Heritage sectors have often been early adopters of available computational technology, the use of such methods to answer novel research questions often depends on close relationships with those in the computational sciences to ensure that technologies can be applied with enough specificity to be useful to a certain case or domain. How can we best build such interdisciplinary research projects to ensure success? How can the field commonly called Digital Humanities help us to explore and push against disciplinary boundaries?

In the lecture, Professor Terras demonstrated some of the leading-edge work that has been carried out at UCL Centre for Digital Humanities and its related partner institutions including the Great Parchment Book project. She used specific case studies to illustrate the benefits, and common pitfalls, encountered, whilst working in large scale, interdisciplinary teams, and explore how a centre such as UCL Centre for Digital Humanities could work as a catalyst within a research institution to encourage people to undertake such activities. She also addressed the issue of how universities and external partners support such resource intensive experimentation.

Professor Terras’s talk at Melbourne University looked at issues involving using advanced imaging methods within cultural heritage, particularly regarding the relationship the resulting model has to the primary historical text. Using the Great Parchment Book as a focus, she asked how we can best integrate multi-modal imaging into our humanities research practices? What issues are there for both research and practice? More details are available here.

Professor Terras is also speaking at the University of Western Australia in Sydney at a Digital Life Seminar.

Is digitising historical texts a bad idea?

Posted on

A recent debate online has been examining whether digitising historical texts is a bad idea. The Great Parchment Book project was put forward as evidence in support of the positive reasons for digitising texts. As  Professor Melissa Terras, Director of the UCL Centre for Digital Humanities and Great Parchment Book project partner says –  “its really good to see the Great Parchment Book changing people’s perceptions of what digitisation can do!”

The wow factor!

Posted on

Our colleagues at UCL, Kazim Pal and Tim Weyrich, in collaboration with Olga Sorkine-Hornung’s group at ETH Zurich, have put together this video to present the ground-breaking interactive method they have developed to digitally restore severely damaged historical parchments based on their work on the Great Parchment Book. The response of those here at LMA was “Wow!” both when we first watched the video and on subsequent viewings.

You can see the amazing results of the method when applied to the Great Parchment Book in the sample of new and improved enhanced images we have uploaded for folios A1r, B18r, H4r, K3r, N2r, N3r and Q1r. Here are the images for K3r as an example with the original image on the left and new, improved flattened image on the right.

 K3r originalk3r flattened

It will take us some time to digitally flatten and upload all the improved images using the method developed by UCL: we’ll keep you posted about progress.

If you want to know more about how they did it, Kazim Pal, Christian Schüller, Daniele Panozzo, Olga Sorkine-Hornung and Tim Weyrich have published the method in an academic paper entitiled “Content-Aware Surface Parameterization for Interactive Restoration of Historical Documents” which will appear in Computer Graphics Forum (Proc. Eurographics), 33(2), 9 pages, 2014.

 Wow!

Spot the difference!

Posted on

We have now finished uploading on to the website all the original images of the Great Parchment Book folios, and enhanced images for at least two thirds of the folios.

The original images are of the folios in their original state before the conservation treatments were carried out. The enhanced images show the folios after both the conservation treatment which was carried out to facilitate the imaging process, and the advanced imaging work carried out by UCL.

Can you spot the difference between an original folio and an enhanced folio? The enhanced folio often looks very different owing to the way the imaging process has flattened the folios to reveal the text. Read more about the imaging process under Project history.

Exploring and Flattening Parchments Interactively

Posted on

We recently had our paper, Interactive Exploration and Flattening of Deformed Historical Documents, accepted for publication in the Computer Graphics Forum and to be presented at Eurographics 2013.

Our procedure begins by capturing a set of high resolution photographs of the pages of the book, and generating from them a detailed 3D scan of each page. Typically we need between 40 and 60 images per folio to capture every fold and crease in sufficient detail. Using these scans we attempt to “virtually restore” the pages and produce undistorted images of the pages.

Three pages of the Great Parchment Book. Top: our reconstructed surface model. Bottom: the models textured with images of the text. The surface models show the level of distortion the parchment has suffered, which differs greatly from folio to folio.

Three pages of the Great Parchment Book. Top: our reconstructed surface model. Bottom: the models textured with images of the text. The surface models show the level of distortion the parchment has suffered, which differs greatly from folio to folio.

Having generated scans for the majority of the pages in the book, we realized that producing a globally flattened and undistorted image of a page is not always possible for the more damaged pages due to the sheer variety and complexity of the deformations present.

To get around this problem we instead created an interactive browser application, effectively a “Google Earth for documents”. Google Earth allows users to navigate over the surface of the earth following lines of latitude and longitude, and always see a locally flat map of the region of the earth they are looking at. In a similar way, our viewer allows users to navigate over the surface of the page following lines of text, and see a locally undistorted image of the region of the page currently in view. One of the key insights here is that flattening multiple small, local regions of a page is much simpler than flattening the entire page at once.

We also understand the importance in the digital cultural heritage field of being able to trust digital representations of artifacts. To help users gauge the quality of the reconstruction and be more confident in what they read, our application includes a “provenance feature” which allows them to compare the 3D scan and the original photographs which were used to generate the scan. For every point on the scan surface, the application can display an original input photograph next to it which allows the user to verify what they are seeing in the scan.

Left: A region of a reconstruction of a page, containing a suspect marking which looks like it might have been introduced by an error in the reconstruction process. Right: One of the original photographs, looking at the same region of the page. We can see that the marking is in fact present on the page.

Right: One of the original photographs, looking at the same region of the page. We can see that the marking is in fact present on the page.

Our application will soon be used as an additional tool for the transcription of the Great Parchment Book and possibly later as a means of dissemination of the book’s content.

Virtual flattening

Posted on

Alongside all the conventional conservation work happening on the book, here at UCL we are experimenting with ways to “virtually restore” the book using a mix of imaging, computer vision, and computer graphics techniques.

Our approach is two-fold. First create a virtual 3D model of each page, and second flatten the 3D model into a 2D plane. It sounds fairly simple but is deceptively complex.

Creating detailed models of the pages requires a careful imaging process to try to get inside every crease and fold and capture every letter at as high a resolution as possible. The result is a set of 50 or so high-resolution images (for each page of the book). These are fed into a pipeline of computer programmes which (after a considerable amount of processing time) generates the 3D model.

Then comes the problem of flattening the page in a sensible way. At first glance, it would seem that we want to just “unfold” the page as you would a crumpled piece of paper. However, the way the pages are distorted is not like crumpling a piece of paper and so there is no nice and easy way to “unfold” them. So now the problem becomes “how can we flatten the page into a 2D plane in such a way that the text does not become distorted”, and that is what we are trying to solve at the moment.
