Carol Harter is the longest-serving President of UNLV, from 1995 until 2006. The campus experienced unprecedented growth during that time, including the addition of a new, very large library. Harter grew the campus from 19,000 to 28,000 students, added 23 new or completely renovated buildings to the campus, and with a student-centered focus, added more than 100 new degree programs. Two professional schools, the Dental School and Boyd School of Law, added greatly to the prestige and academic Top Tier status of UNLV.

Her partnership with Glenn Schaeffer, former president of the Mandalay Resort Group, assisted in the early work of the Black Mountain Institute (BMI) Modern Letters program. BMI is an international think tank dedicated to advancing literary and cross-cultural dialogue. This was an important goal to Harter and Schaeffer, who were both literature majors. Harter also discusses many community members who made an impact on UNLV including Joe Crowley and Dr. Juanita Fain.
