When you find resources that are highly relevant to your research topic, you can use citation chaining to find further relevant resources. There are two ways of identifying further relevant resources:
Backward citation chaining - identify older resources published on your research topic
Forward citation chaining - identify more recent resources published on your research topic
When you have a resource that is relevant to your research topic, you can find older resources on the same topic by reviewing the reference section located at the end of the article.

You must access and review the primary source of information to do your due diligence as a scholar. You should read and evaluate the primary source, rather than cite it secondarily, to ensure accuracy.
When you have a resource that is relevant to your research topic, you can find more recently published articles on the same topic. Specifically, search for resources that cited your relevant resource in their reference section.
You can use multiple databases and Google Scholar to search using forward citation chaining. The benefit of using a database over Google Scholar is that it focuses your citation chaining search to topics relevant to that database. The benefit of using Google Scholar over a database is that it typically identifies the most citations.
