When on campus, the DMU network automatically authenticates you with our information providers using IP addresses. We encourage you to use the links on the library site as these URLs are customized for DMU access, but we acknowledge this is not always a requirement to access resources when on campus. You can Google your way into some of our resources thanks to IP verification.
However, when off-campus, you must use the URL's provided by the library. Why? Because URL's to library resources are unique. Every URL is constructed in a way the first directs you to the OpenAthens, which acts almost like proxy server.
"In computer networks, a proxy server is a server (a computer system or an application) that acts as an intermediary for requests from clients seeking resources from other servers." Proxy server.

Thank you, Wikipedia.
OpenAthens recognizes whether or not you on the DMU campus thanks to IP verification. If you are on campus then you go straight to the resource. If you are off-campus, OpenAthens will request your DMU credentials before permitting access to the resource. OpenAthens allows the library to permit access to licensed resources to the DMU community while preventing access to these same resources to the general public.
