Subject and genre headings

1. Every fully cataloged record in the CCS database must have at least one LCSH heading, or at least one 655 heading if no 600-651 headings apply.
2. Every record for a single work of prose fiction in the CCS database must have at least one LCSH heading AND any 655 headings that are appropriate; every record for a textual collection in the CCS database must have at least one 655 heading.
3. Always add a 655 for concepts that are expressed in 6XX $v, when one is authorized. Continue using 6XX $v.
4. Be as specific as possible (e.g. $v Fiction --> 655 Science fiction; use of specific 655 Pop-up books & 655 Textured books instead of general 655 Toy and movable books)
5. Always code "[Language] language materials" as, e.g. "655 _7 French language materials.|2local", never as, e.g. "650 _1 French language materials." or "655 _1 French language materials."
6. Use $v Specimens only for realia.
