Library of Congress (LC) subject headings are special, standardized words and phrases which describe the primary subject(s) on which a book focuses. Searching by subject heading rather than by keyword often allows you to look for books on a particular topic more efficiently.
Since LC subject headings are included in a book's catalog record, looking at the records you get from a keyword search can help you identify appropriate subject headings. Ask A Librarian for help with LC subject searching.
Below are just a few examples of subject headings you will find in the STLCC Catalog. Dates appearing in history subject headings usually reflect significant historical events.
