Policy and formulation

Used in Folger records for the accession number

• All vault materials added to the collection receive a 6-digit accession number. The call numbers of most printed rare materials are based on the accession number. Items acquired before this practice may have four-digit accession numbers, case numbers, the name of a person, or a date.
• Case numbers are 4-digit numbers that go to the low 2000s. Record the number preceded by 'cs', no space. Example: ǂe cs1493 (a parallel series of case numbers from 1 through 128 have circles around them, and are referred to as "circle case" numbers. Use parentheses to indicate the circle. Example: ǂe cs(25))
• Accession numbers 3001 through 7029 were assigned between October 1930 and the end of August 1938. (A previous version of these instructions incorrectly said "The books donated by Henry N. Paul were given 4-digit accession numbers in the 6xxx range" but in fact, the Paul donation received accession numbers 5921-6176, 6735-6858, and 6897-6900. Incorrect Henry N. Paul former owner access points may therefore be present in Hamnet).
• Separate the units of date-based accession numbers with a period. Example: ǂe 12.30.44
• 'F' or 'ac' usually precedes the six-digit accession number or accession date as written in the item. Record the 6-digit number only. Example ǂe 256644
• If item in hand lacks a case or accession number, record ǂe No case or accession number present
• In the case of framed art or other material where an accession number would be hidden, record ǂe No case or accession number visible
