Shelf-marks and what they mean
Shelf-marks are always based on a classification system. The system used by the Campus Library is the Regensburger Verbundklassifikation (RVK) (in german only).

The final line of many shelf-marks includes minuses, pluses or brackets. These are often misinterpreted, so please read this explanation to avoid any misunderstandings.
