It would be wonderful to get the 70's El Rodeo available online....
As of Tuesday, October 23, 2012, DigitalCommons@CalPoly now provides access to all 47 El Rodeo Yearbooks from 1927-1942, 1946-1971, 1977-1980, and 1990 and 4 summer supplements (1955-1958).
Publication was suspended between 1943-1945 during World War II, 1972-1976, and 1981-1989.
We hope you enjoy this new digital access! You can still see the yearbooks in University Archives.
