One option to locate topic-related sources is to start with a high-quality source and look at the references to identify additional sources, You can also check to see if the source has been cited since it was published. This process is called cited reference searching.
Here is how it works. Start with a high-quality source, such as a peer-reviewed journal article or foundational source. Review the references that the author(s) cited to identify other high-quality sources that you might want to use. Next, check to see if other authors cited the original article since it was published. By looking at both older and more current topic-related sources, you can learn about the history of the topic and some of the current research conversations associated with the topic.
