English: The University of Montana (UM) was founded in 1893 and its first yearbook, the Sentinel, was produced in 1904. Over the next 80 years, this yearbook expanded to include photographs and stories documenting all aspects of life at UM. The Sentinel is a rich source of information about the history and culture of the University. It covers unique UM events like Aber Day, the Foresters Ball, and the annual Griz-Cat game along with student government, Greek life, intramurals, Homecoming, student clubs and organizations, and much more. The Sentinel was published from 1904-1972 and again from 1987-1989.
