Library of Congress subject headings could be an interesting source of data for this project, and can give you hints on what terms you might search in other resources. This information is easily findable via search engine, or ask me for help tracking it down. For more information about how subject headings reinforce certain ideas about categories, check out the documentary "Change the Subject".
