Shelfmark Hs. 42a in the Martinus-Bibliothek in Mainz comprises 25 black and white photographs of palimpsest leaves from Hs. 42. The photographs were taken at Abbey Beuron before 1919. For the photography the manuscript was unbound in order to take images of the individual leaves, which had been folded to double leaves and bound to form the codex.
