Some publishers provide what is known as a “persistent link,” a consistent URL that will link directly to the article.

Ovid provides DOI for their articles, but if that proves problematic another option is something they call "Email Jumpstart." Right-click the Email Jumpstart link and copy the URL. For off-campus access, add http://proxy.lib.uiowa.edu/login?url=
