Hyphens, En Dashes, Em Dashes

Q. In “University of California Berkeley,” for example, which mark would you place before “Berkeley”: hyphen, en dash, or comma? My preference would be either the en dash or the comma, but never the hyphen. What say you?

A. The University of California apparently prefers the comma, so that’s what we’d advise. See also CMOS 6.87.
