URSUS is the combined library catalog for the entire University of Maine system. You can search the entire system, or select University of Southern Maine Libraries in the drop-down.
Other helpful tips:
Most databases, as well as URSUS and MaineCat, assign subjects to books and articles. A subject is a designated word or phrase that describes an idea or concept and groups all articles or books about that concept together.
There are many ways you can get research materials from other libraries. In the vast majority of cases, there is no charge to you for this service!
