The library works with Google so you can find library sources in addition to the free stuff on the web.
When you're on campus and using a computer connected to the Tulane network, Google Scholar will automatically connect you to articles that are available through the library.
When you're not on campus, you can set Google Scholar Settings to identify the sources available through the library. Click Settings, then Library Links, and type in Tulane University. Save your settings.
When the full-text doesn't appear with the Google Scholar results, click "More" beneath the item description.
Then click "Check for availability" which works like clicking TU Link. It will give you options to link full-text or request an item through interlibrary loan.
