Apologies to our readers from the University of Cincinnati. Apparently, it is abbreviated simply UC, not U. of C. as I had asserted before; apparently only my alma matter is pretentious enough to do that.
Then again, it may just be a regional thing, like those soda/pop/coke conversation you had at your first week at college. The University of Michigan is almost always "U. of M." -- never "MU" and rarely "UM". Likewise with the University of Illinois and the University of Minnesota. Of course, Indiana is "IU" and Wisconsin is "UW", so what do I know.
