Act 45 (Appendix A) of the 1995 Regular Session of the Louisiana Legislature
III. University and System Name Guidelines
All institutions within the University of Louisiana System are to comply with the
following precepts and guidelines set forth to govern and coordinate the use of the University
of Louisiana name and logo:
A. As previously stated, there is no main campus for the University of Louisiana
System. Any designation of or reference to a member institution as “flagship,”
“lead,” “main,” or other similar descriptor is prohibited.
B. The use of the University of Louisiana System logo and/or the phrase “University of
Louisiana System” by an institution for commercial purposes or general use must
have prior approval by the Board of Supervisors for the University of Louisiana
System.
C. The use of the two-letter University of Louisiana abbreviation, “UL,” and/or the
phrase “U of L” are prohibited by the university or any of its affiliated organizations
(alumni associations, development foundations, bookstores, etc.). For academic,
public relations, athletic, as well as other purposes not specified, the use of the
University of Louisiana abbreviation must always include the abbreviation for the
municipal location of the institution. For example, ULR is appropriate for University
of Louisiana at Rayne.
D. All uses of the name “University of Louisiana” must be followed by the word “at”
and the institution’s geographic location. No typographic variations within the name
are permitted. The word “at” must be no less than 50% and the geographic location
must not exceed 100% nor be less than 80% of the University of Louisiana name.
Any institutional use of “University of Louisiana” without the “at” and geographic
location is prohibited
This is in place to prevent other UL schools from sounding like a satellite campus.
For instance, LSU has LSU-Shreveport, LSU-Alexandria... When someone refers to ULL as UL, it make ULM sound like a satellite campus.
