E-sequence, a collaborative project between a number of European academic institutions, has a display interface for images of manuscripts, their transcription, and both translations and audio renditions of the text. As of Jan. 2013 there were 9 mss of Notker chants and additional audio files of the chants sung by Ordo virtutum, from Cod. Sang. 381, 484, 382, 376, 378, 380, 546, and Cod. Einsiedeln, StiftsB 121.
Although focused on medieval manuscripts, the project offers digital classicists ideas on how texts might be rendered and published.
