Having been founded in 1587, Leiden University Library in 1595 issued the first printed catalogue of its holdings: Nomenclator autorum omnium, quorum libri vel manuscripti, vel typis expressi exstant in Bibliotheca Academiae Lugduno-Batavae (List of all Authors whose Books, Whether Manuscript or Printed, are Available in Leiden University Library). This was the first published catalogue of any institutional library.
When I searched in August 2019 there did not appear to be a digital facsimile of this catalogue available.
