"Research can be difficult, but you don't have to start from scratch if you follow the clues left by scholars who have gone before you!"
As you conduct your research, you will need to make note of the additional resources (book, book chapter, journal article) you identify in the bibliographies, references, notes and footnotes of the sources you are using. The reason for this? Because this is one of the best ways to further your research.
Example:
Let's say you found this article:
Nicholson, S., & Segura, G. (2012). Who's the Party of the People? Economic Populism and the U.S. Public's Beliefs About Political Parties. Political Behavior, 34(2), 369-389.

And you read it and it is just great for your research. The next thing to do is look at the list of references and follow-up on any that look relevant. This is a great way to build your bibliography, to find like materials.
