The University of Missouri system has 4 campuses that I know of:
Main Campus (Columbia)
UMSL (St. Louis)
UMKC (Kansas City)
and what WAS UMR (Rolla)
Rolla was originally Missouri School of Mines, and then joined the UM system as the "engineering campus". On January 1, UM-Rolla will be renamed Missouri S & T = Missouri University of Science & Technology. (I suppose "MIT" was taken....)
I think there were / are 5 directional State Universities....
SW, SE, Central, NW, and NE (fairly symmetric).
In an effort to ditch the "directional school stigma", the largest one Southwest Missouri State (in Springfield) became "Missouri State".
"SEMo" is in Cape Girardeau, and Missourians refer to SEMo as "Cape".
Central is in Warrensburg.
Northeast (in Kirksville) changed its name to Truman State, and has gotten some national recognition from USNews for great educational value for the $$$.
Northwest (in Maryville) tried to jump to the U of Missouri system, and become UM - Northwest. The State Legislature killed that move in 2006.
A better new name for the Rolla campus would be "The University of Missouri Institute of Science and Technology" - their official short name would be Missouri S&T (or Missouri-S&T).
I think a merger of all the state-supported universities in Missouri into the University of Missouri system could happen in the long run. Lincoln, Harris-Stowe State, and Truman State would be called UM-name of person for which institution is named (UM-Lincoln, UM-Harris/Stowe, UM-Truman - similar to how one of the U of Wisconsin campuses [UW-Stout] is named). All the others (NWMSU, SEMO, Missouri State, Central MO, MO Southern, MO Western) would all be named for the city they are located in (UM-Maryville, UM-Cape Girardeau, UM- Springfield, UM-Warrensburg, UM-Joplin, UM-St. Joseph).
