U.C. San Diego is something I've heard/read as well, but U of CA? I don't think anyone uses that.
With the University of California system there is no at in the title. University letterhead generally includes the names of all campuses. When a specific campus is sending mail, the entire title of that campus will be specified at top. So for UCSD, it would say "University of California, San Diego". Under the seal is the address, which would be: "San Diego, California 9????-????" (I don't know the zip for UCSD).

Aren't Verses Programmers generally referred to as Composers?
