text: Subject Heading is defined as the most specific word or group of words that captures the essence of the subject or one of the subjects of a book or other library material (e.g. serial, sound recording, moving image, cartographic material, manuscript, computer file, e-resource etc.) which is selected from a subject heading list containing the preferred subject access terms (controlled vocabulary) and assigned as an added entry in the bibliographic record which works as an access point and enables the work to be searched and retrieved by subject from the library catalog database.
