When you have an article with references, you can see if a particular reference is available by looking the journal's name up at the link below. Then you can use the volume and date information to navigate to the article. If we don't have access to that journal, we usually can get it from another library.
We subscribe to dozens of databases that contain articles. Try some of the ones listed below or chat with a librarian or your professor for suggestions of how and where to search. You can also get recommendations by clicking Research Guides on the library's homepage. Click on a Subject Guide related to your topic and look for the Articles tab for appropriate databases.
