Start your search for scholarly articles at the PSU Library catalog by selecting the Resource Type, Articles or Newspaper Articles or Peer Reviewed Journals (just search one type of article at a time). Limit your search to the last five to ten years to see the most current research on your topic. Be sure to Sign In so that you can add relevant articles to your eShelf for easy access.

These databases are great places to start your research!
