What is an archive collection?
A collection refers to a group of documents which are combined into a unit according to logically comprehensible criteria such as their origin, their context of origin (provenance principle), their subject matter (pertinence principle), formal or material characteristics (collection items, selections). Collections function as the central level of the tectonics of an archive.
As a structuring unit, the holdings represent the central organizing and structural element of an archive by guaranteeing the logically comprehensible mutual delimitation of document groups. The establishment of an inventory and the transparency of the principles on which it is based are prerequisites for finding archival records. Orientation in the holdings is guaranteed by indexing, i.e. organizing and indexing the holdings in overviews and finding aids (find book).
