"Standford University" has about 400 hits, so it is next.
"Dartmouth University" actually existed as a part of an effort to force "Dartmouth College" to be public. US Supreme Court got involved. But my guess is a good number of the hits are wrong. I'll take a look.
"California University" may get some hits to 90210. more likely would be google hits on pages with strings "attended University of Southern California, University of Texas", so may be too many false positives...
University of North Carolina Charlotte
The page starts "The University of North Carolina at Charlotte, also known as UNC Charlotte, UNCC, or Charlotte, ..." . While it would be inappropriate to delete UNCC because there are lots of people who use that albeit improperly, I think that *adding* what the formal abbreviation is (with reference to UNC Charlotte's marketing web page) would be appropriate.
As for why? If I saw it in a paper encyclopedia, I'd write the company. Since it is Wikipedia, I'd fix it myself. I live in the DC area and have worked with the students at that school (as well as others in DC/MD) so I've had to check it in my own work.
I've got a semi-automated tool, so it isn't quite so bad, but I've got to do each language separately with "John Hopkins University Press" showing up in references in languages that I didn't know *existed*, it was an adventure.
