Seat Booking

Book a seat in our subject libraries and use the Mannheim reservation system MARS to manage your seat bookings.

Personal data

The privacy information was provided to me.

Please cancel your seat booking if you are unable to attend. The seat can then be reserved by other users. This is the only way we can ensure that as many people as possible can use the subject libraries.


  • To book a seat in our subject libraries you need to hold an ecUM or a library card. Please log in with your Uni-ID and password. First-year students need to unlock their ecUM to have access to the University Library.
  • You can only book a seat for yourself, not for others.
  • Spontaneous seat bookings are still possible for the current day, provided that free seats are available and you have not yet claimed a seat on that day. The traffic light informs about seats currently bookable for members of the University.
  • You can interrupt your library visit for a maximum of one hour, after which your place will be released for other users. Please note that if you exceed the time limit, you will not be able to check in on the same day, even if there are still seats available.
  • Multiple bookings for one calendar day are not possible.
  • For members of the University of Mannheim, seat bookings are limited to three active bookings in one or more subject libraries within the next 14 days.
  • For members of cooperating institutions or users with a library card, seat bookings are limited to one active booking in a subject library.
  • As soon as a day booked by you has started, you can make another booking for a day within the next 14 days.
  • In order to change a seat booking, please confirm your cancellation before continuing to make another booking.
  • The green marking shows on which days and in which subject libraries seats are available. This information shows the booking status at the time the page is called up.

Please inform yourself about the hygiene regulations (PDF, 107 KB) in the subject libraries.
