Accessions and Openings of Records
New accessions are Federal records and other historical material, such as Presidential papers, recently added to the National Archives. These materials may not be available for research until they have been processed. Processing includes arranging and placing the materials in proper containers, describing the content of the materials in a finding aid, and reviewing the materials for any donor or general restrictions.
Openings describe those historical materials that have been processed or declassified and are now ready for researchers to use.
