“Collection” and “Accession” are words used all the time in the archival profession. In Buswell Library Archives & Specials Collections, an accession is material received from a single donor, usually an individual or an organization. It might be a single folder or hundred of boxes, with only a general inventory to use as a finding aid.  A collection is a set of materials (perhaps including paper-based records, photographs, audio or video recordings, etc.) that has been fully arranged and described. Most of our collections have been formed from several accessions. Here in the Archives & Special Collections, both collections and accessions are open for research (unless there have been donor-requested restrictions) but the lack of a complete finding aid and access points can make accessions difficult to locate or use for research.
