In 1482 Jakob Lauber, the librarian at the time, began to compile a loans register for the holdings of the library of the Carthusian Monastery of Basel. This register was continued after Lauber's tenure until 1527. The loans register was set up according to the shelfmark letters A to I, and it even was possible to record volumes on loan that had no shelfmark. Borrowed books were listed with the exact shelfmark under the corresponding letter; after the book's return, the entry was crossed out.
