Research databases are tools that help you search for scientific literature (journal articles, book chapters, and conference presentations/ papers), on a particular topic.
Librarians review them to see if they have quality information from reliable sources. You should check each individual source based on the requirements of your instructor. For more information about refereed or peer reviewed journal articles see the Peer Review tab.
If you need help searching the databases, use the tools to help you set up your search.
For tips on limiting to Peer Reviewed or Refereed literature, check the Peer Review tab.
