OCLC has a wonderful search that includes the National Union Catalog, however unlike the sources above OCLC is available only through libraries. Check out your local public or academic library they probably have it available. It can locate may items and they can be requested on loan from other libraries.
Walk around your local library. Try sections 393 and 306 if your library uses the Dewey Decimal system or GT31xx ( Manners and Customs) and GN70xx (Anthropology) if the Library of Congress system is used.
Always, remember you can ask a librarian. All the ones I know
are friendly, helpful people.
