Subject and genre headings

1. Every fully cataloged record in the CCS database must have at least one 600-651 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 600-651 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
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. Always code genre headings in 655, regardless of thesaurus of origin (e.g. "655 Large type books" not "650 Large type books")
7. Do not include age, audience, gender, geographic, or national origin elements in 655 (e.g. "655 Short stories" instead of "Short stories, American" or "Short stories, African (French)"; "655 Graphic novels" instead of "Graphic novels|zJapan"; "655 Science fiction" instead of "Science fiction|xWomen authors"; "Songs" instead of "Children’s songs"; "655 Fiction" instead of "Youth’s writings")
