This collection contains documents, photographs, publications and other material on the Associated Students of the University of California at Riverside (ASUCR), an undergraduate student government body. Materials in the collection include information on amendments to the ASUCR Election Code and the constitution and bylaws of ASUCR. Of note is a poster documenting ASUCR's support for the students protesting for free speech at UC Berkeley in 1969.

The collection consists of materials from Jim Toledano, an alumni of UC Riverside who later served as the UCR Alumni Association President and UC Alumni Regent. Items in the collection relate both to Toledano's time as a student at UC Riverside from 1964-1968, as well as his service as part of the UCR Alumni Association from 1979-1985, and include course catalogs, meeting minutes, event fliers, correspondence, coursework, and campus publications.
