Policy and formulation

  • Use controlled vocabularies whenever possible. Prefer AAT terms; if appropriate AAT terms do not exist, consult RBMS as a backup. If appropriate terms are not found in either of these vocabularies, use LCSH, TGM, or local terms.
    • Generally, follow the genre/form term in the subfield ǂa (and century subdivisions in ǂy, when used) with a period. Exception: terms from all RBMS vocabularies except the RBMS-Genre list are followed by their list name in parentheses, e.g., "Prayer books" vs. "Prize books (Provenance)". In this case, the closing parentheses is the final punctuation mark; do not follow with a period. (See example 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. Note that terms from RBMS-Printing and RBMS-Publishing have separate source codes, even though they are published as a combined thesaurus (RBMS Printing & Publishing Evidence).
  • As of 2014, Folger catalogers do not subdivide genre/form terms (exception: for manuscripts, subdivide 655s by century, per Curator of Manuscripts).
  • 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.
