If you are looking for books, videos or ebooks, use the PCC Library Search.
If you are looking for articles in the EBSCO collection from magazines such as Smithsonian, or Scholarly (Peer-reviewed) journals (mixed up) then use the PCC Library Search, but click on the "Articles" tab before entering your search terms.
If you are looking for Scholarly Articles (Peer-Reviewed) on the subject, you can be safe using JSTOR, but it doesn't have articles from the last few years. BE SURE TO CLICK THE "ARTICLES" CHECKBOX BEFORE SEARCHING. Otherwise you will get a lot of book reviews and other material that isn't really a peer-reviewed article.
