The library's holdings are shelved in classified order and for the most part in open stacks in the various departmental libraries (shelf classification).
You may take the items from the shelves and present them at one the circulation desks for the circulation transaction. For borrowing items it is required to show your library card. All items borrowed are charged to your loan account.
Before you look for the items on the shelf please check the availability in the library catalogue first. There you will find out, whether the book is on the shelf or on loan. At this point you can release a reservation for the item as well.
If a library item of interest to you is currently on loan, you have the option to make a reservation for it. Reservations can be made in the library catalogue. Do not forget to check beforehand, whether the library holds more circulating and accessible copies and thus the reservation may be obsolete!
When the requested item is returned, an email or postal notification with information on where and when to collect the item will be sent. The reservations will be saved for a 7-day period. For a cost free notification by email, enter your email address in your loan account. For postal notifications on reservations, postal charges amounting to 0.80 EUR will be added to your account.
In your loan account you can track filled or outstanding reservations and as the case may be, cancel them.
The circulation desks are located in the entrance areas of each departmental library. At these desks you can return and check out library items and collect reserved books. After the circulation transaction you will get a receipt which indicates all books you have borrowed and the respective loan periods. Please be aware of the due dates! The library is obliged by federal law to impose overdue fees already the very next day after the end of a loan period.
Item return is possible in any of the departmental libraries. You will get a receipt which you should check for correctness and keep for possible objections on your part.
The personnel will of course assist you and be of help in case of questions and problems concerning library issues personally or by phone.
