BISAC subject headings : including merchandising theme codes
"BISAC subjects describe the topical content of a book and do not cover non-content-oriented ways of grouping titles (such as "gift books"). Other fields in BISAC communications formats (language, audience, age range, grade range, format/binding/packaging, supplementary format/binding/packaging, merchandising themes) are available to help describe a book in ways not covered by the subject list."--Page 3
