You can use the catalog to help you find more books on a topic by using the record (what you see when you click on a book title after you search) to narrow or redefine your search:
1. Keyword Search - Search for books by words or short phrases that you know are related to your topic or topics,
2. Browse Results - Find one or two books that look the most on topic or useful,
3. Search by the LC Subjects - LC Subjects are the specific topics assigned to each book in the catalog. You'll usually see several for each book and they look like this:
Food habits -- United States -- Sex differences
Click on the subject that looks best to find more books assigned to that subject and other related LC Subjects.
4. Keep searching! Continue searching like this this as you find more LC subjects related to your research. Keep track of which subjects are useful and which aren't. Try the subjects in the databases you search, they're often similar to how articles are categorized.
Political Science & Law
Social Sciences & Sociology
But there is more in other areas of the library. Think about your research and try multiple search strategies to find materials across disciplines.
