One of the best ways to utilize Journal Locator is when you are attempting to track down an article or a citation that you found via another source (otherwise known as backward/forward treeing).
Journal Locator will tell you if we have access to a specific article/journal, and it will tell you what years/volumes/issues the library has access to as well as in what format (print or online via a database).
If you have a citation for an article, use Publication Finder to see whether the library has full-text access to the journal in which the article appears. Search for the title of the journal.
Journal Finder lists all the journals, magazines, and newspapers that the library subscribes to and provides links to those that are online.
If we don't have the journal for the article you need you may request the article through interlibrary loan.
