The Digital Image Archive of Medieval Music (DIAMM)

The purpose of the Digital Image Archive of Medieval Music (DIAMM) is to obtain and archive directly-captured digital images of European sources of medieval polyphonic music. Where there is damage that makes these sources difficult to read, levels of digital restoration are also undertaken on copies of the original images to improve legibility and scholarly access. The project has created a new permanent electronic archive of these images, both to facilitate detailed study of this music and its sources, and to assure their permanent preservation. The sources archived include all the fragmentary sources of polyphony up to 1550 in the UK (and almost all of these are available for study through this website); all the 'complete' manuscripts in the UK; a small number of important representative manuscripts from continental Europe; a significant portion of fragments 1300-1450 from Belgium, France, Italy, Germany and Spain.

Source material
"Fragmentary and complete manuscript sources (usually parchment) of medieval polyphonic music from libraries throughout Europe, the USA and Australia. There are approx 220 contributing archives (libraries, record offices, private collections, academic institutions) from 11 countries. All digital images remain the intellectual property of the owner of the original source, and DIAMM archives and delivers online under licence from the owners. DIAMM is not an image supply service: scholars requiring copies of the original images must apply as usual to the owner of the document".
