Policy and formulation

• Use controlled vocabularies whenever possible.
  • Use the Getty's Art and Architecture Thesaurus (AAT) if a suitable term exists
  • Use the RBMS Controlled Vocabulary for Rare Materials Cataloging if AAT does not have an appropriate term
  • If neither has the appropriate term, use the Library of Congress Thesaurus for Graphic Materials (TGM) or Library of Congress Genre/Form Terms.
  • As a last resort, use Library of Congress Subject Headings (LCSH) or a local term.
• Generally, follow the genre/form term in the subfield ǂa (or ǂx, when used) with a period. Exception: a closing parentheses is the final punctuation mark; do not follow with a period. (See examples below.)
• Always include a subfield ǂ2 to specify the source of the term, using an abbreviation from the Genre/Form Code and Term Source Codes List.
• For copy-specific genres/forms, include subfield ǂ5 DFo
• As of 2014, Folger catalogers do not subdivide genre/form terms (exception: for art, subdivide 655s for Portraits into $x Male or $x Female if applicable).
• Be accurate when providing terms; consult established scope notes and Folger scope notes. However, be wary of being too specific, and include broader terms when this may support user access (e.g., use both "Presentation inscriptions" and "Authors' presentation inscriptions"). Needs discussion
• When deciding whether or not it's worth providing controlled access to copy-specific information, ask yourself "If I were a researcher interested in [possible term], would I be disappointed if this came up from the vault?" For example, someone studying manicules would probably want to see a book with just one example of a manicule, but someone interested in annotations probably wouldn't appreciate discovering that the book they'd been waiting for only had one or two annotations.
