A permalink is a URL (web address) that will take you back to a specific webpage or article.  When you want to link to a particular book or article in a webpage or iCollege site, look for a permalink. 
 
Why not just copy the hyperlink in the address bar?  

When you use many of our research databases, including the Discover search and EBSCO databases, the URL displayed in the address bar is particular to that session. Copying and reusing that link later will not get you back to the same page. Instead, look for a "permalink" icon among the tools on the page.  The permalink should get you back to the same page. Permalinks to GSU library resources will prompt users for their GSU credentials when necessary to be in compliance with our licensing agreements.
