The library computer banks of USS Voyager contained information from the Starfleet database.

The library computer was accessed to learn about the Federation's attempt to create the Omega molecule. (VOY: "The Omega Directive")

Access to Voyager's library computer was granted to the Borg drone One, after Seven of Nine had activated the drone's linguistic database, and allowed him to assimilate information. (VOY: "Drone")

Seven later downloaded portions of Voyager's library computer directly into her cortical implants through the use of a cortical processing subunit. However, she stopped using the device after it produced several adverse effects. (VOY: "The Voyager Conspiracy")
