Digital Image Archive of Medieval Music inaugurated the series DIAMM facsimiles in 2010 with The Eton choirbook. Edited by Magnus Williamson, the book presents a full-color facsimile edition of Eton College Library MS 178, an iconic source of English choral polyphony composed during the late fifteenth and early sixteenth centuries that has been continuously in the possession of Eton College since it was first copied for use in the college chapel in the early 1500s.
