When you find the resource you want to link, click on the title and a new page will open. Under "Tools," click on "Permalink." A window with the permalink will open above the resource title.
In JSTOR, a permalink is referred to as a Stable URL. To locate the Stable URL for a resource, click the title of the resource - a new page will open and then you can find the Stable URL under the title.
In all ProQuest databases, a permalink is referred to as a DocumentURL. To locate the DocumentURL for a resource, click the title of the resource - a new page will open and then you can click the "Details" tab (sometimes this tab is paired with the abstract).
Scroll down and you should see the Document URL near the bottom of the page.
