Searching for books from the self-service areas is possible not only via using verbal expressions for the OPAC database, but also by using a systematic approach.
Herefore, we use the "Regensburger Verbundklassifikation" (RVK = Regensburg Union Classification). It is the basis of our shelf mark system for all self-service areas of Greifswald University Library.
