If you want a permalink to ProQuest content, you could copy the permalinks found on OneSearch or by finding the direct URL from any ProQuest databases.
On the right hand side of the content you want to link to, you should see a circle with ellipses that says "All Options" a box should appear and the permalink will be at the top.
You could also find the permalink under the Abstract/Details tab of the record you are looking at. It is called a Document URL.
