EZProxy is a service that authenticates you as an MTSU user and allows you to access electronic resources, such as database, articles, journals, or streaming media.
If you start your research from somewhere other than the library's website, you can install the EZProxy Bookmarklet on your browser. This snippet of code will send you through the library's EZProxy server, where you'll be prompted to login, and then you can access the content directly from the resource, as opposed the library's site.
