Five manuscripts of the Bamberg tradition survive (Bamberg, lit. 22, 23, 24, 25, 26). Bamberg, lit. 23 was used by Hesbert in his Corpus Antiphonalium Officii (it is his manuscript "B"), but of these five manuscripts, only Bamberg, lit. 25 is written in staff notation (the other four consist of non-diastematic neumes). As the only one transcribable into modern notation, it is a valuable key to the musical tradition of Bamberg. Unfortunately, Bamberg, lit. 25 is incomplete; numerous folios are missing from the codex. Nevertheless, it has its treasures: most notably, the Office of Afra (83r-87r) and the Translation of Kunegunde (97r-99v). The latter is printed in full in Analecta hymnica, vol. 26, pp. 224-227.
Differentiae are designated by a letter that indicates the pitch on which the differentia ends; where necessary, additional numbers are used to distinguish differentiae of the same mode that end on the same pitch.
Each chant not found in CAO is assigned an arbitrary number prefixed by "bam".
