In 2365, Captain Wil Thoms was the commanding officer of this ship. In that year, the Lexington was assigned a planetary exploration mission in Sector 028. The ship was listed on the Starship Deploy Status chart that was on display in the courtroom of Starbase 173. (TNG: "The Measure Of A Man", okudagram)
Many new graduates of Starfleet Academy in 2369 considered the Lexington a plum assignment and fiercely competed for an assignment aboard her. Doctor Elizabeth Lense, who graduated as a valedictorian from the Starfleet Medical Academy that year, was assigned as the Lexington's new chief medical officer. Thereafter, the Lexington embarked on an interstellar charting mission. (DS9: "Explorers")
In 2373, the Lexington fought against the second Borg invasion at the Battle of Sector 001. After the initial contact with the cube, the Lexington's first casualty report listed 96 dead, and 22 wounded. (Star Trek: First Contact)

The Lexington's appearance in "Explorers" was reused footage of the USS Prometheus from "Second Sight". Despite its appearance as a Nebula-class, it was described as a Galaxy-class starship in the episode's script. This Lexington's registry was stated as being "NCC-61832" in the Star Trek Encyclopedia (4th ed., vol. 2, p. 331).
The Encyclopedia (4th ed., vol. 1, p. 462) and StarTrek.com described the Lexington from "Thine Own Self" to be an Excelsior-class starship with the registry number NCC-14427. As the ship was not seen in that episode, it would be unnecessary to think it wasn't the Nebula-class Lexington as it was already in service by 2369 according to "Explorers".
The closed captioning on the VHS version of Star Trek: First Contact referred to the Lexicon and not the Lexington. This had been changed on the closed captioning for the Special Collector's Edition DVD. However, the audio does sound like it could be either one, so the presence of either ship was possible.
The Constitution-class USS Lexington was named for an United States aircraft carrier that fought in the Pacific theater during World War II. This was probably the case for the 24th century Lexington. (Encyclopedia (4th ed., vol. 1, p. 462))
In the second issue of the Doctor Who crossover comic Star Trek: The Next Generation - Doctor Who: Assimilation², the Lexington was sent with additional equipment and full taskforce of engineers to aid in the mining operation on Naia VII following a mining disaster.
In the Star Trek: Starfleet Corps of Engineers eBook Hard Crash, the Lexington, along with the USS Enterprise-E were called by the USS da Vinci in 2376 to assist them following the crash of an alien ship on the planet Intar.
