Berlin has a large number of public and private libraries which provide a very good research network for academic studies.
The Universitätsbibliothek (UB) of Freie Universitaet Brelin is located at Garystraße 39, 14195 Berlin. Books can be checked out for four weeks. Extensions are possible as long as someone else has not already put in a request for the same book.
The UB also has a large reading room where numerous important reference books (dictionaries, encyclopaedias, etc.) can be used. These books may not be taken out of the reference area.
In addition to the main library, there are departmental libraries (Bereichsbibliotheken) that are useful to students on a day-to-day basis. The most attractive of these is the newly built Philological Library designed by Sir Norman Foster. These libraries are not lending libraries for the most part, which means reading must be done on site. However, there may be exceptions.
The other universities and colleges in Berlin also have their own libraries which can be used by students of Freie Universitaet Berlin.
Particularly useful is the Staatsbibliothek, better known as the Stabi, which is by far the largest library in Berlin. Haus 1 is on Unter den Linden and Haus 2 in the Kulturforum on Potsdamer Straße, opposite the Philharmonie. The Stabi is a lending library and also has a large reading room to accommodate a large collection of non-lendable books (Handapparat). Unlike the university libraries you cannot use a student ID card to take out books at the Stabi. In order to take out books from the Stabi or use the catalogues, a Stabi library card is required. This can be obtained (for a fee) by going to the lending desk on the ground floor in Haus 2 (please note that you will need your passport and a copy of your police registration/ Meldebescheinigung).
The Berliner Zentralkatalog is also situated on the ground floor of Haus 2. This centralized card catalog lists books in all Berlin libraries, except those at Freie Universitaet Berlin and the Stabi itself.
