The Leibniz Institute for Contemporary History library collections have been made accessible via various catalogs over the past decades:
The online catalog has been the main tool for searching the library since 1996. This includes both the holdings of the IfZ Munich library as well as the reference library in Berlin. Since the old card catalogs were converted, the online catalog has included the entire collection of the IfZ library. The holdings of the press collection and the printed materials collection of the archive are successively being incorporated into the online catalogs.
The geographical catalog is a remnant of the old card catalog that was maintained through 1995. The information there could not be completely transferred to the current system. The geographical catalog is therefore still of importance for a comprehensive search for older literature on places outside of Germany (countries, regions, cities, etc.) and on the states of Germany.
The IfZ library card catalog was compiled and made accessible to the world in printed form by an American publishing house between 1967 and 1973. This edition is now of little use for research purposes, while it does however document the international reputation that the library had attained less than two decades after it was founded.
