I wasted some time today trying to confirm the official full spelling of "UCLA." Several English-Japanese Dictionaries give "University of California at Los Angeles," but I vaguely remembered that at least some of the University of California campuses use a comma instead of "at."
I spent ten or fifteen minutes wandering around UCLA's vast Web site, but its proprietors seem to assume that everyone already knows what "UCLA" stands for, as the full spelling did not appear in any of the official statements or press releases that I looked at. The closest I got was this historical note:
Third- and fourth-year courses were soon added, the first class of 300 students was graduated in 1925, and by 1927 the Southern Branch had earned its new name: University of California at Los Angeles (the "at" became a comma in 1958).
I finally found one English-Japanese dictionary that gives the correct spelling, Progressive:
University of California, Los Angeles カリフォルニア大学ロサンゼルス校.
