Pandectae Brandeburgicae Continentes I. Bibliothecam. . . Auctorum impressorum [!] & Manuscr. partem. . . nomina plurimorum, Anonymorum, Pseudonymorum & c. explicata. . . II. Indicem materiarum praecipuarum, of which only the first volume (A-B) was issued by Christoph Hendreich in Berlin in 1699, was an attempt to produce a universal author bibliography of books and manuscripts. It was named for Frederick William, the Great Elector of Brandenburg, whom Hendreich served as librarian. The first volume covering letters A and B listed 50,000 works by 15,000 authors, reflective of the significant growth in recorded information by the end of the seventeenth century. The author, who died in 1702, did not live to complete any further volumes.
