The Library has around 15,000 rare and valuable books, that are not available for browsing by the general public. This rare books collection is in a special climate-controlled and secure room.
If you need a book and the call number begins with the letter R, then please go to the employees at the Information Desk. In most cases the desired book can be obtained immediately. In some cases, however, such as evenings or Saturdays we need advance notice in order to have the book(s) available in the Media Centre's reading room for you.
You can send us an e-mail in advance or also reach us by telephone (88-2871), when you need a particular book.
The Wessenberg-Bibliothek also contains a large number of rare books.
Books which have call numbers that begin with "4" or "5" are arranged in the Media Centre but are not freely accessible due to the fragility and/or value of the books. They can, however, be borrowed. They should be checked out in the Media Centre.
