Demographic group terms that describe the characteristics of the intended audiences and/or creator/contributors of resources that will be useful for discovery purposes may be assigned from any controlled vocabulary, including, but not limited to, the Library of Congress Demographic Group Terms (LCDGT) , Library of Congress Subject Headings (LCSH), Homosaurus, African Studies Thesaurus, First Nations House of Learning Subject Headings, Chicano Thesaurus for Indexing Chicano Materials, A Women’s thesaurus, National Museum of the American Indian Reference Lists, International Thesaurus of Refugee Terminology, or any other controlled vocabulary with a MARC code recognized by Harvard’s Library Technology Systems (see HOLLIS data elements LTS wiki page). A complete list of MARC source codes may be found either at Subject Heading and Term Source Codes. (Please note that Harvard activates source codes on a case by case basis. If you discover an unrecognized, yet valid MARC code for a vocabulary you wish to use, please submit a request to Library Technology Systems for approval.)
In addition to the documentation on the websites listed above, LCDGT terms have extensive documentation, particularly in the Demographic Group Terms Manual.
