Catalogue change and Interlibrary Loan

Due to an internal change in the catalogue system of the GBV it will not be possible to issue interlibrary loan orders from 22.03.2019 - 26.03.2019. The delivery of items that you order close to this date might be delayed.

From March, 25th 2019, when the new catalogue (K10plus) will finally be released, it is possible that unexpected problems arrive while using the OPAC. We hope that no big issue will influence your work. We are trying to make the switch as smooth as possible.

Lighting in the Zeughaus

For technical reasons, the shelf lighting on the 1st and 2nd floor of the Zeughaus must urgently be renewed. It will be replaced by emergency lighting until further notice. Regrettably, the emergency lighting does not reach the usual level of brightness. We ask for your understanding for this necessary action.
