Bibliothek fuer Bildungsgeschichtliche Forschung, Berlin, Germany, a fine library for scholars working on the history of education in Germany. The library has over 700,000 volumes, and offers comfortable workspaces for visiting scholars. I would add that the library also contains an archive that holds the personal files of several important European educators including Pestalozzi and Froebel. It is also easily accessible via the U-Bahn (Warschauer Strasse). Web site:
