When you find a book that looks good, scroll down to the bottom of the screen, and you’ll see the Library of Congress subject headings. You can click on these links to find more books on that subject. You can also use these subject headings when searching databases, WorldCat, and many digital collections on the internet.
Learn some basic Library of Congress Subject Headings for your topic.
Look for Bibliographies & Indexes in Subject Headings. These can be useful resources.
Library of Congress subject headings often used for primary sources:
WorldCat is a catalog of most libraries in the U.S. & Canada and many from other countries. Find books, DVDs, web sites, musical scores, archival material and more.
There are two versions of WorldCat, the subscription version from First Search, which is below and which I recommend, and the free version. If you find something you need while searching in WorldCat, and we don't own it, we can usually get it from another library. See InterLibrary Loan (ILL) to learn more. One great feature of the First Search version is that it automatically fills out your ILL request form.
