The Repertorium of Urban Moser, librarian of the Carthusian
Monastery of Basel, is a register of the library holdings of the
Carthusian Monastery of Basel, alphabetically arranged by authors,
titles and topics. Since Moser’s successor Georg Carpentarius
changed the shelfmark of various volumes, around 1520 he added a
shelfmark concordance to the catalog, so that this alphabetical
register could still be used. Thus the alphabetical register and
the shelf lists (Basel, UB, AR I 2 and AR I 3) could be used in
complement.
