(Req, Rep, Getty Vocabularies/LOC Authorities/other)
Subject provides a way to record what a work of art is about or what a photograph is of. Subject analysis for images can be incredibly difficult when doing image cataloging, but ask yourself one question… What do you see? The answer will often will lead to an appropriate subject heading, (including elements found in abstract paintings where the composition includes no representative subject matter, but rather only lines and color).
Use the English language equivalent from the thesaurus, unless none exist. Try to be as specific as possible. If the photograph is of a rose use 'rose' rather than 'flower' for a subject. If you don't know the specific type of flower you can use the generic 'flower' as a subject.
It is acceptable for subject terms to repeat or overlap with other items such as title or work type. Subjects may be regarded as separate from other descriptive fields in this regard. Subjects should be recorded for all works, even abstract or architectural works which seem to have no implied narrative or subject matter.
For more information on Subject see CCO, pages 215-229.
This is a field to record the display value for the subjects associated with the work. Use values from Getty AAT, Library of Congress or other indexes or thesauri to create terms. Please do not transcribe ampersands (&), replace these in authorities with “and.” Subjects with ampersands cannot be recalled in the Library from the primary Subject field.
If there are alternative terms, spellings, or phases for the same Subject record them here, especially those terms offered in the AAT, LOC, or other authority. Use the Subject variant field to record the singular form of a subject if the preferred is plural. If there is a known alternative term not listed in the authorities, but that would be useful to include, please do.
