XENO-02884/1 is a computer file kept in Starfleet ships that details everything the United Federation of Planets knows about the parasitic race known as the Bluegill and their actions. Amongst the data are reports submitted by Starfleet personnel such as Christopher Pike, Jean-Luc Picard, Gregory Quinn and Beverly Crusher. A high security clearance is needed to access the file.
In 2376, Admiral Leonard James Akaar gave Kira Nerys his security verification to gain access to the file so she could find a way to fight the parasite who had control of the USS Gryphon. (DS9 novel: Lesser Evil)
