What are papers and archives?
Libraries commonly use the term "papers" for collections of an individual's original documents and personal effects. "Papers" covers many formats, such as manuscripts, drafts, diaries, journals, audio and video recordings, books, and artifacts (e.g., eyeglasses, musical instruments) that belonged to the individual. Archives usually refers to the records of an organization, though there are exceptions. “Archival” carries a different connotation, and would apply to individuals’ papers and other collections.
