The Library has provided a tool that takes the permanent URL, adds the proxy prefix to it, and allows you to copy the newly created URL to paste into your reading list, your syllabus, your email, wherever you want to provide it for your students.
The Link Builder tool is easy to find and use.
From the Library's home page, in the 'Help & Services' menu, mouse over "Teaching and Classroom Support" section and choose "Persistent Links to Library Content".
Paste the permanent URL into the box, click Create Link! and then copy the resulting link. This is the link you will paste into your reading list, etc.
