The University Library of Tübingen provides a number of databases for staff and members of the university. The databases listed here are all licensed by the UB and are thus freely accessible via the network of the University of Tübingen or externally via your ZDV account and a VPN client. You can find an installation manual here.
You can find further databases, both licensed and freely accessible, in the network, via the database information system DBIS. You will find all relevant databases under the heading "Oriental Studies". It is also worth reviewing the databases of the fields of "education", "political science" or "history".
The following links lead to a content description of the database in DBIS. Another click on the name leads to the database:
Encyclopaedia of Islam
U.S. Intelligence on the Middle East, 1945-2009
