You can't always return to an online document by copying the URL in the address bar of the page you're viewing.
To find URLs that always link to a document, use a permanent link, also called a durable or persistent URL - these don't change or expire after you leave them.
Persistent links are designed to connect directly to an online document. Use them on a bibliography, course syllabus or reading list.
This tutorial covers how to find and use a permanent link that you can provide to others.

You've found an online document, and now you want to be able to provide others with a link to that document. Find a reliable permanent link.
There's one more step you need to take before you give this link to someone: authentication. In many cases, only authorized users will be able to access a document.
Consider your audience and try to provide a link that works for them. If it's someone with Trent credentials who may be working from off-campus, include the proxy prefix.
The proxy prefix allows authorized Trent users access to documents that are available because our Library provides access.
Keep in mind that the proxy server is only useful for Library resources.
The only way to know if the link will work for someone else is to open a new & different browser, and paste the link into the address. It has to be a different browser so that it has no memory of how you got there and it isn't already logged into the proxy server. You'd be surprised what browser histories remember!
If you don't have more than one browser on your computer, consider adding one. It's a good idea to have more than one browser, because many database features perform better in one or another browser.
You could also try using a different computer or mobile device to check your link.
