My professor sent us a link to the AMA Manual of Style, but I can't access the content from off-campus
Your professor may have sent the wrong link to your resource. It's important that you access all of the library's electronic resources through the library's website at www.usciences.edu/library. Although you can find links to our electronic resources via Google, the links on the library website are unique.
When you are off-campus you'll know you are entering via the correct link because you'll see the login screen (below) before entering an database or journal; any other login screen is incorrect and will not recognize your credentials. Note: you will not have to enter your credentials before entering every resource; the login is only needed again after a long period of inactivity.
