Volume 5

Volume 5 was a digital archive at CTU Los Angeles.

Day 5
During the hostage crisis at Ontario Airport during Day 5, Lynn McGill asked to revise the transcriptions of the phone conversations CTU had with Jack Bauer. At some point, he asked Chloe O'Brian to unlock Volume 5 so he could access the archives and verify something he found on the transcripts. Chloe quickly did, giving Lynn access to the volume.
