4 .		Sometimes you will want to find the right subject terms (the controlled vocabulary, as it sometimes is called) for your terms. How can you do it? One way is to find the Library of Congress Guide to Subject Headings in the reference collection. But often you are not in your library when you are searching. Here's an optional way to find the subject terms. Select one term from your key word search that looks like it might be related to your topic. (You should find "Automobiles -- Maintenance and repair" if you have searched for the key words "car and repair.") If the Subject heading is at the bottom of the page, you should be able to click on it. You should see the results of your "subject search" on the screen. (And you didn't have to use the big reference book in your library to do your search). Locate subject terms for your research topic by using this technique. Report your results in the box below.   To create paragraphs in your essay response, type <p> at the beginning of the paragraph, and </p> at the end.
