A permalink is a permanent, stable link to an item within a database. This is not the same as a URL or web address.
Because we pay for access to databases, vendors use these links and other security to make sure only authorized users are accessing university resources. If you take the web address from the database, the page will expire and the link will no longer work after a short period of time.
Instead, you can use the permalink or the digital object identifier (doi) to provide long-term access to articles.
