The Starfleet yearbook was an annual publication by Starfleet Academy documenting all students attending the Academy in a given year.
It also included photographs. In 2152, hoping not to be recognized by Tavek as not being Captain Archer, Trip Tucker told Hoshi Sato he hoped that Starfleet yearbook photos were not in the Vulcan database. (ENT: "The Seventh")
In 2368, Boothby didn't recall Jean-Luc Picard when Wesley Crusher initially mentioned him; however, when Crusher showed the groundskeeper an old yearbook photo, it jogged his memory. (TNG: "The Game")
