Domain-specific¶
- Cross-listed Classification
- The structural commitments of cross-listed classification are: a controlled class vocabulary with explicit codes; a multi-parent assignment relation from work to class (one work, multiple classes, not a hierarchy-enforced single parent); an institutional rule specifying when secondary codes are warranted versus optional versus discouraged; an exchange syntax that carries multiple codes in a record (comma-separated MSC codes in article metadata, MARC subfield repetition in library records)

“Terms indicating the genre, form, and/or physical characteristics of the materials being described.”
- In LCSH and MARC practice, genre and form terms are carried in field 655 and in the LCSH genre/form headings vocabulary
- Geographic Facet
- In LCSH practice this is the geographic subdivision (MARC subfield $z, as in 650 $a Agriculture $z Iowa), with a place that is itself the heading carried in MARC field 651; OCLC FAST exposes it as `fast:geographic`; the Getty TGN underlies art and architectural catalog place terms

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Read against the text for 4 of 4 citations: 1 supported, 3 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
