The catalogue

In February 1619, four years after the library was established, librarian Mulerius wrote a list of the books present. There are two copies of this list. One is the librarian's working copy, with the title Academicorum Syllabus Librorum and the year 1619 stamped in gold on the front cover. In this copy, the catalogue of 1619 is followed by later acquisitions made during the terms of office of Mulerius and his successors up to the eighteenth century. The second one is a beautifully written and decorated copy, intended to be shown to important visitors, donors, and potential sponsors. The list of February 1619 contains 219 titles in the working copy, while the calligraphic copy has 204 titles in 403 volumes. Most of them are in folio format, a few are quartos.
