Use subjects in this section for works of a general nature or for works about the topics found in this section (note that there is a subheading "Reference" in most other sections and some sections also have a subheading "Dictionaries & Terminology").

Subjects in this section may be used with those in other sections for reference works on topics not found in this section, but it is recommended that topical subjects be assigned first: for example, a bibliography of medical books could be assigned "MEDICAL / Reference" and "REFERENCE / Bibliographies & Indexes"; a bibliography of books about pediatrics could be assigned "MEDICAL / Pediatrics", "MEDICAL / Reference" and "REFERENCE / Bibliographies & Indexes".
