We have different “libraries” for our items – manuscripts, books, pamphlets, photographs, artifacts, etc. We can receive a single donation and it will include one, some or all of the above. We accession them all together under the one donor, then as they get cataloged they are entered into their different “libraries” – books and pamphlets into library, manuscripts into archives, photographs into photos and artifacts into objects. Then they are stored separately. The left side of the “accession includes” box indicates which “library” an item was entered into – which helps us to see how a single donation was separated out for individual care needs. Does that make sense?
