The Illustrated Booklets were published by Oregon Agricultural College (OAC) during the 1910s and 1920s to promote and publicize the College to potential students and Oregon residents, and to provide vocational guidance to youth and young adults. In addition to general information about academic and research programs offered by the College, booklets focusing on agriculture, engineering, music, science, landscape architecture, business, and home economics were produced. Several booklets also promoted opportunities for women at OAC, and two booklets published during World War I highlighted military training and the roles played by OAC students and faculty in the war effort. One booklet described campus buildings and facilities as of 1922 and another was dedicated solely to the newly completed Memorial Union.

The booklets include numerous photographs depicting campus buildings and scenes, students in classrooms and laboratories, and student activities. The first bulletin was described as "elegant...handsomely illustrated...[and] beautifully printed."

This digital collection includes 29 booklets.
