In 1988 a time capsule was buried in front of the Hurley Administration Building. It had been assembled to commemorate the occasion of the seventh name change for the university. The name was changed to the University of North Texas from North Texas State University. It was buried alongside the 1962 time capsule, which documented the first year the school was a university.
The capsule was opened in April 2015 during the celebration of University Day. The capsule was composed of a copper box encased in steel reinforced concrete. Among the items contained in the capsule were books, a VHS tape of President Hurley, memorabilia from campus blood drives, and a color print of the 1988 Drumline.
