Notes to availability

Regular system maintenance processes with different running times are primarily carried out on weekends between 23:00 and 03:00. Unscheduled maintenance will be announced in a timely manner.

Reminder fees:
– Per reminder (1st to 3rd reminder) € 2.00
– Overrun fee per tape and day 0,20 €

Note regarding reminder mails:
The reminder e-mails are a voluntary service of the University Library and are intended to help you avoid missing loan deadlines. The University Library cannot guarantee the safe and timely delivery of e-mails. You are responsible for meeting your own loan deadlines. For this reason, we must charge fees for overdue loan periods in all cases (regardless of whether or not you received a reminder email).

Since the primary means of communication for loan transactions is via email, please make sure that you have an up-to-date email address in your library account in your own interest. Changes of the mail address (please with a copy of a photo ID attached) can be requested via mail to or .
