From the NLI BLog:
Over the past while the National Library of Ireland has been developing its enhanced catalogue and what better way to demonstrate its capabilities than with one of its most important collections, the James Joyce manuscripts. After a long time of planning, organising, cataloguing, digitising, building the technical infrastructure, testing and re-testing, the Library can happily announce that many of the literary and personal manuscripts of James Joyce in its possession are now available online.
It took a while and great effort to get to this point, with staff from across the NLI each contributing to the project in their own area of expertise. The complete list of Joyce manuscripts here at the National Library was analysed, as were any existing finding aids (the detailed lists of collection contents). With much welcome advice from the Manuscripts team, the materials were then catalogued – a mix of both original cataloguing where no detailed finding aids existed, and a conversion project where information from the finding aids was mapped and hundreds of online records created for each item and branch of an archive. To give examples of the latter, findings aids existed for the two largest collections, the Joyce Papers 2002 (Collection List No. 68) compiled by Peter Kenny and the Joyce-Léon Papers (The James Joyce-Paul Léon Papers: A Catalogue) compiled by Catherine Fahy. All the information found in each can now be viewed online, either in individual records or in context as part of an archival tree.
The complete post has MUCH MORE information about the project including the fact that many records include images to accompany the records.
