Bibliographies can be useful--especially for identifying books and archival collections.
Although book bibliographies and online indexes are essential tools in research, your most vital resource, once you have settled on a topic, will be the Bibliographies (AKA References or Works Cited) at the end of the best scholarly articles that you find on your topic. A good scholar makes a thorough literature review a large part of their research process. And that literature review is one of the aspects of an academic article that is examined by peer reviewers and editors.
So when you find one good article on the topic you are interested in, be sure to track as many of the salient resources that you can from that author's bibliography.
As an example, here is the title of one article, plus just the first few references from the multi-page bibliography.
You might find pages and pages of great leads at the end of the article, so explore them! Check the eJournal Locator and the Online Catalog (OPAC) to see if Sawyer Library owns the items of interest. And ask for assistance at the Reference Desk, as needed.
