Use a reference source (such as an encyclopedia) to gather background information about your topic. It's best to rely on a published source because you can have more trust in the accuracy of information there than in Wikipedia. If you do use Wikipedia, consult the References at the bottom of the page. These Reference often cite published works you can also consult.
To find "reference" sources you can search the library catalog and limit to "Reference" as I do here:
Take note of terminology used in Subject Headings and use it to inform your search terms and to further explore the catalog.
2. When you locate books in the stacks, browse the entire area. You always find something else! Look at tables of content and indices to assess if books will be helfpul to you.
3. Use citations to find more sources.
4. Search Discover to find more books, and articles. Use the facets on the left hand side to refine your search results. You can limit to scholarly articles there. You can even look up an article title in Discover. For example Also try searching some of the more specific terminology and concepts you are noting. Remember articles are written about very specific questions.
5. Research is an iterative process. As you refine your topic and articulate more specific research questions, you need to find additional sources. Return to reference books to look up new terminology. Do more searches in the library catalog and Discover.
6. Make a list of what information you still want to find and what sources you think would be likely to have it.
