DIAMM Digital Image Archive of Medieval Music
Contains more than 14,000 digital images of medieval and early modern manuscripts of polyphony, the simultaneous performance of multiple melodies. Combining high-quality images of music manuscripts alongside detailed metadata (including Description, Bibliography, Commentary, and Contributors), DIAMM is an extensive resource for scholars and librarians of medieval music and manuscripts. This vast collection of images not only facilitates musicological research, but digitally preserves the content of parchment manuscripts which are otherwise vulnerable to damage and illegibility over time. To get the most from this resource, visitors will need to register for a free account.
