Policy and formulation

For new cataloging, apply at least one genre/form term. In general, any valid genre term is fair game. This is in contrast to previous practice (before about 2014) when terms were applied from a pre-selected list. Form terms not in the Connexion Constant Data set should only be applied cautiously, after due consideration.
See Connexion Bibliographic Constant Data for standard Folger preferred terms.
- Use controlled vocabularies; if no suitable terms can be found in a published vocabulary, consider creating a local term and submitting to RBMS or another appropriate thesaurus.
- Use the RBMS Controlled Vocabulary for Rare Materials Cataloging if a suitable term exists.
- Use the Getty's Art and Architecture Thesaurus (AAT) if a suitable term isn't found in CVRMC.
- 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.
Follow the genre/form term in the subfield ǂa (or ǂx, when used) with ending punctuation, a period or closing parenthesis but not both. (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 Comedies and Plays. Some narrower constant data records contain clusters to do this automatically.
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 brief annotations.
