This publication includes two essays--one dealing with 16th-century German book printer Jakob Köbel and including an extensive bibliography of his works and the other a study of two 14th-century library catalogues. The wrappers of this copy are detached (but present), lightly soiled and a bit tattered, but the printed portions are intact. A plate attached inside the front wrapper indicates that this copy came from the reference library of H. P. Kraus. The sections are detached from one another, but the leaves show minimal wear or soiling. A table of contents for the first four issues of Centralblatt für Bibliothekswesensupplements is included with this copy.
