There are lots of ways to search for articles by topic. Here are a few good starting places:
Use Summon. Click "Peer Reviewed Publications" and "Items With Full Text Online" in the Advanced menu to limit to scholarly articles that are available online.
Choose from a list of databases by subject. On the library homepage, click the Databases tab at the top, then "Browse databases by subject, type or vendor." Then use the Subjects drop-down list.
See if a librarian has created a research guide for your topic.
