Issued in 1572 by the Augsburg printer Michael Mangerus, Catalogus bibliothecae Hieremiae Martii, Doctoris Medici Augustani, the catalogue of the private library of the Augsburg physician and scholar, Jeremias Martius (c. 1535- c. 1585), may be the earliest printed catalogue of a private library.

When I searched for the catalogue of Martius's library in October 2020 I located two copies in WorldCat: one in the Bayerische Staatsbibliothek and the other in the Staats- und Stadbibliothek Augsburg. Neither appeared to have been digitized. It appeared from the collation published in WorldCat that the catalogue consisted of only 22 pages.
Because publication of private library catalogues was a new idea at the time the question that comes to mind is why Martius undertook this project. Perhaps examination of the printed catalogue will provide an explanation.
Besides this issue, there appears to be no extant portrait of Martius. He did, however, publish or edit several works cited WorldCat at this link.
