The paper presents basic approaches to managing archival resources in the Presidential library (Saint-Petersburg, Russia). All resources in the collection are described using the RUSMARC format (national implementation of UNIMARC), which provides sufficient instruments to keep the hierarchical structure of archival description and to give detailed characteristics of the materials.
The holdings of Slovenian libraries also include photographs, which can be catalogued and included in the COBIB shared bibliographic database. Photographs as a medium are very specific compared to other types of library material, as one of their characteristics is that the data required for bibliographic description is missing. However, cataloguing in the COMARC format still enables adequate description.
