konvolut
Konvolut is a term used in German-speaking archives, libraries, and museums to describe a bundle or collection of documents or objects kept together as a single unit because they share a common provenance or subject relation. A Konvolut is not necessarily a formally organized archival series; it is often a heterogeneous assemblage assembled by a creator or by later custodians. The unit may consist of materials that originated with a single person, institution, or event, but individual items within it may differ in type, date, and function.
In archival description a Konvolut is described with scope and contents, provenance, dates, and physical condition.
Contents and characteristics vary widely, but a Konvolut often includes letters, notes, invoices, drawings, photographs, clippings,
Etymology: Konvolut derives from Latin convolutus, meaning rolled together or wound up, via German usage.
