Ebsco-Hosted Databases (Academic Search Premier, etc) call PURL's Permalinks. Here are the steps for finding them.
1. In your search results list select the title of the article to be taken to the article record.
2. Once in the record, select the Permalink Link on the lower right hand side of the page under the header Tools.
3. When you select the Permalink link it opens up a new box at the top of the record with the Permalink. Just copy and paste that Permalink to use as a the PURL. Notice that it has the proxy string attached already!
