Los Angeles Comprehensive Bibliographic Database Thesaurus

"The LACBD Thesaurus was compiled from the subject indexes that accompany the two bibliographies to provide a controlled vocabulary that spans one hundred years of Los Angeles subject matter. This specificity means that some terms and names one might expect in a thesaurus about Los Angeles will not be present. Likewise, general subject hierarchies that may have been constructed to place orphan terms were not developed, although the current structure allows for future development. Part one of the LACBD thesaurus is a common subject thesaurus.
