We inform you that from August 17 planned hardware and software upgrades of virtual libraries based on Primo are being carried out. Virtual libraries are not available during the system upgrade. For searches in library catalogs, placing hold requests of books, and renewals of holds we recommend using electronic catalogs of libraries based on the library system Aleph. Preliminary, the system upgrade will take until August 28. We will notify you if this deadline changes. 

We apologize for any inconvenience.
