Include scholarly and specialized articles from a specific discipline
To choose a database, think about what department on campus would have scholars researching your topic, then use the "All Subjects" dropdown menu on the databases page to find that department, or find the guide for that subject (ex. PsycINFO for Psychology topics)
If you are looking for a specific type of information, other than scholarly articles (ex. historical newspapers, audiovisual, etc.) you can also look at databases by type of information they contain by using the "all database types" dropdown menu.
