Subject Headings

Library of Congress Subject Headings are the words and phrases that you will use to do a subject search in Catalyst (as opposed to a word search, where you may use any words you like). Although Physics is a Library of Congress Subject Heading, you will probably get better results if you are more specific. If you are interested in thermodynamics for instance, use the subject heading Thermodynamics, Be careful in your word choices--some words and phrases that may seem very natural to you will not be Library of Congress Subject Headings.

It is often helpful to do a keyword search on your topic, and, once you find an appropriate source, examine the subject headings. You may then conduct a subject search by clicking on the linked subject heading in Catalyst. If you cannot find a source using a keyword search, ask a librarian for help.
