If you often do your research from off-campus, you can add the proxy bookmarklet to your browser's bookmarks toolbar. In many cases, the bookmarklet lets you log into the proxy (which will give you access to content that UT Libraries own) without having to browse from the UT Libraries website.
Use Ulrich's to determine if an article is from a peer-review journal. First, type the journal name in the search bar, and select it from the results. Then, look in the Basic Description table for the Refereed and Content Type sections to determine whether a journal is scholarly and/or peer-reviewed. (Ulrich's uses the term refereed, which is the same as peer-reviewed.)
