This facsimile edition is the fourth in the series by the Digital Image Archive of Medieval Music (DIAMM
), which aims to publish facsimiles of the highest quality at a reasonable price.
DIAMM, founded by Margaret Bent and Andrew Wadley and managed by Julia Craig-McFeely, is an online archive designed to create high-quality digital images of thousands of medieval music manuscripts, thus preserving fragile and rare materials unavailable elsewhere and providing scholars access to said images.
Two functions of DIAMM's site will be of significant importance to researchers and librarians: first, the collation of and access to excellent images of medieval music (a far cry from the microfilm upon which scholars relied even a decade ago), and second, the metadata collected with the images, which includes information on archives, sources and bibliographic information related to the sources, and the music contained within the sources.
Although both are essentially source-based methods of access at this point, DIAMM promises a more open method of access based on additional meta-data that exists in DIAMM's database but which is currently hidden to users.
Searching is unfortunately relatively basic at this point, although as previously mentioned upcoming changes to the site will allow for more comprehensive searching of DIAMM's database.
Each source record encourages researchers to contact DIAMM for additions or corrections to the record, which at this point are uploaded at periodic intervals throughout the year (the ability to make changes to the database publicly available in real time is expected in the forthcoming upgrade).
Any time a user adds a note or transcription to an image, a link to that note is created in My DIAMM. Private notes may be edited or deleted; one cannot delete public comments.
