Many library subscription services create on-the-fly links to articles, chapters, and films that are not stable. If you use an on-the-fly link, anyone who clicks on it will be directed to a useless login page from the vendor that supplied the resource to our library rather than the university login page for our subscription to that resource.
What you want to use is a stable link (also called a permalink or persistent URL or PURL). Some of our collections provide an easy copy & paste option to create a permalink to a resource. Look for a link icon while you are viewing the resource. If it's not obvious where to get the stable link/permalink/PURL, visit this library guide to creating permalinks, and scroll to the vendor for whichever collection you are using. Instructions for obtaining a permalink can be found there.
