To find out what terms are LC subject headings, switch to the Classic Catalog and use the “Subject beginning with…” search.

Use WorldCat UMD to search for books, journals, government documents, and other resources owned by the University of Maryland Libraries. WorldCat can help you discover materials that are useful for your research.
The basic search function is a key word search that matches your search terms to words in the catalog records in WorldCat. Enter key words related to your research to start searching.
A basic search is very broad and may return many results that are not relevant to your research. To refine your search and return more precise results, click on Advanced Search. The advanced search options allow you to search by keyword, author, title, or subject, as well as to limit your search by fields such as library, year, format, or language.
To do a “browse” search, i.e., to get an alphabetical listing of authors, titles, and subject headings for items in the USMAI libraries, click on “Classic Catalog” and use the drop down menu to select your search method. Keep in mind that the Classic Catalog only returns results from the USMAI libraries.
