A new library system, what changes for you?

The university library has been using a new library system since the 20th of April 2020. The most important consequences of the new system for you as a library user are that you can request and renew library material in a different way. The library started offering her collection through the world wide catalog WorldCat in 2018. Now this is the place where you request, renew and check the status on the materials you have on loan as well.
This page provides a global overview of the changes and will be updated in the coming weeks.

PLEASE NOTE: Due to the Corona crisis, library services are limited. Please check the most recent information about the limited services of the library on our homepage.

What has changed?

  • You request library material and renew your loans in WorldCat, no longer in the old library system (Aleph).
  • The way in which the availability of items in our physical collection is shown in WorldCat looks different than before.
  • You have more options to search and filter your search results. This is because WorldCat is able to "read" the new library system (WMS) better than the old one (Aleph). Tip: use Advanced Search.
  • You can no longer perform search actions in old library system (Aleph).
