Information on Circulation

Borrowing and Returning Media

The collection of books in the library is sorted systematically and is open to access. In order to find the book you are looking for please make use of our Katalog plus.
In your catalogue search you can find out where the medium is located in the library by clicking on the title and you can see if this medium is available for loan or not, if necessary place a loan reservation.

In our open access library you can pick up the books you need yourself and take them to one of the circulation desks for borrowing together with your library card or the USiCard activated for library use. In the Main Library Adolf-Reichwein-Straße (AR) and in the branch library Unteres Schloss (US) there are also self-service terminals available.
Media from our stacks and audio-visual media from the media collection have to be ordered via the Katalog plus.

Media with a white or green call number tag can be borrowed from the library. Media with a red call number tag are part of the non-lending collection and cannot be borrowed from the library.

The lending period is usually 60 days. If the item in question has been reserved by another library user this period is shortened and you will be informed about the new lending period via e-mail. Please adhere to the lending periods since you will be charged a fine for overdue loans from the first day after the deadline.

Borrowed media are to be tended with due care and to be kept safe from harm of all kind. Please inform us about any damages or markings inside the book before borrowing the item. If damages are noted on return of the item, the lender will be held responsible.

Borrowed  media can be returned at every circulation desk, return by post is also possible.
To avoid complaints please always check your user account.

Please present media with expired lending period at one of our circulation desks to return them or to have the lending period renewed and pay the fines.
Extending the lending period of items from interlibrary loan can only be done by presenting the item in question together with the pink interlibrary loan form at one of the circulation desks.
Extending the lending periods via phone is not possible.

Placing Loan Reservations

If a medium is lent out to another user, you can place a reservation on that item via the button “Vormerken” (“Request”) in the Katalog plus. Beforehand you should check whether the library has more items of the same kind available for loan (maybe in other parts of the library or in one of the branch libraries).

When the item in question is returned you will be informed that the item has been reserved for you and can be picked up at the respective (branch) library.
If you have registered your e-mail address you will be informed free of charge. Postage for information on reserved media sent via mail will be charged to your user account.

In your user account you have an overview over placed reservations and reserved media now available to you ("Ready for pick up"). There you can also delete reservations on media you no longer require.

By reserving media the lending period of the item(s) in question will be shortened. You can find the new due date and thus the new availability date in the overview over your reservations in your user account after 1-2 days.

Fine for Overdue Loans

Please adhere to lending periods for borrowed media since you will be charged a fine for overdue loans from the first day after the deadline. Please note that these fines are due regardless of the time of dispatch and reception of reminders.

The fines for overdue loans are calculated according to the Gebühren- und Entgeltordnung der Universitätsbibliothek Siegen (Charges and compensation regulations of the University Library of Siegen).
The fines for exceeding lending periods per medium are:

  • 1st level of loan period overrun (from the 1st calendar day after the due date): 2.00 €
  • 2nd level of loan period overrun (from the 11th calendar day after the due date): additional 3.00 €
  • 3rd level of loan period overrun (from the 21st calendar day after the due date): additional 5.00 €

These fines, except the ones you have received an official letter for („Leistungsbescheid“), can be paid in cash or via ec-card at the pay machine in the Main Library Adolf-Reichwein-Straße (AR).
Payment of pending charges will lead to immediate exoneration of your user account and includes a receipt.
You will need your library card or library card number for the payment.
In the branch libraries you can pay your charges at the circulation desks.
Please keep in mind:
To borrow a medium implies that your user account is free of charges. Therefore please pay your fees before you borrow a medium.
