1. FIND WORKS WRITTEN BY KEY FIGURES IN A POLITICAL OR SOCIAL MOVEMENT
Also try searching for the major figures in a movement who may have written on the topic (Reference books may give you some ideas of names to try). Chances are that we have some of their works in the library. REMEMBER! Use an AUTHOR search to find material BY a given person. To find material ABOUT a person, use a SUBJECT search. In both cases, enter the last name followed by the first name. You can also search for works written by an organization or political party.
The Library of Congress uses several different terms to indicate primary source material in a catalog record. These include:
Caricatures and cartoons
Therefore, to find primary sources in the catalog, you can also use a combination of your topic keywords and LC subject heading words in a keyword search: try Soviet Union AND sources.
However, not all materials that are primary source materials will have these designations in the catalog, so you should NOT rely only on subject searching to find the materials you need. Also, DO NOT use the LC Subject Heading search for this technique: unless you type the Subject Heading exactly as it appears in the Library of Congress Subject Heading list, you will probably not retrieve anything at all. Stick to keywords.
