Why is Our Collection Important?

The Registrar's Office is the repository for all of the original accession and loan records that date back to the opening of the Museum in 1913. Collections staff and researchers regularly consult our accession files to find background information on objects and specimens in the collections, verify accession numbers, or confirm connections between objects and specimens and the corresponding donors.
