No automatically loan period renewal from 15.02.2021

HNU library has to go back to manual renewal of loan periods:

  • Starting on Monday, 15 February 2021, you will renew your loan periods online by pressing the renewal button in your library account in the library catalogue; there will be no automatic loan period renewals from that day onwards.
  • This does not affect the number of possible renewals (which is 3 for most media): If your current loan period has been automatically renewed twice, you can manually renew it one more time.
  • This does not affect interlibrary loan periods: These are still only renewable by contacting the library team.

The reason for this step backwards is a serious bug in our library system that ignores reservations when renewing automatically. Thus in the current configuration, reservations are almost meaningless. In order to bring back the functionality of this feature, we have to go back to manual renewal, at least for now. This problem will be solved in a future system update and we will bring back automatic renewal after that. But we currently do not have any reliable information on when this will happen.


We are sorry for this step backwards. But we are convinced that this is the right way for customer friendliness – especially for those who are desperately waiting for books and have made their reservations.
