Abstract
Thanks to the efforts of Paul Schrecker and John W. Nason some half century ago, the University of Pennsylvania is home to microfilm reproductions of over one hundred thousand hand-written pages drawn from the collection of Leibniz’s papers presently housed in the Niedersächsische Landesbibliothek, Hannover. The microfilms are to be found on the mezzanine floor of the reference section in the Van Pelt Library and are readily accessible to visitors. Xerox copies may be made, although the Van Pelt Library stresses that the microfilms remain the property of the Niedersächsische Landesbibliothek, and that permission to copy must be obtained from Hannover beforehand.
