There are several ways to search for journal articles. You can start with UC Library Search, using the Articles, Books and more option, which searches all the databases the UCLA Library subscribes to. Or you can go to a specific database, such as APA PsycINFO, Academic Search Complete, PubMed, etc.

If there are subject terms or descriptors, click on those that seem related to your topic to get other articles on the subject.
