When you are looking at an article in a database, the URL (or link) that you see in your browser's address bar is sometimes only active for the length of your search session. This means if you save the link and try to return to the article the next day, you will see an error.

If a database offers a permalink, permanent link, direct link, or bookmark, copy this instead. This is a stable link that will allow you to return to the article or page at a later time. 

If you're trying to re-find an article, search the article title in the "Everything" tab search box on the library website. Still can't locate it? Ask a librarian
