A personal log is a type of log which is used to record a person's personal thoughts about a current mission or life in general, which can be recorded in a personal log by name or as unofficial documentation. It performs a similar function as a diary or journal and is not meant to be read by others. (DS9 episode: "Whispers"; DS9 novel: Saturn's Children)
Captain James T. Kirk often used a personal log to note certain occurrences on the Enterprise that was not required to be documented officially, but would be of concern to him as a commanding officer. In 2268 this included the disappearance of items from a lab, an unusually large number of transfer requests from people serving under Lieutenant Bergdahl , complaints about foodstuffs and other commodities from the ship's stores, personality conflicts, and recreation room gossip. Unlike his official log Kirk did not make entries every day. (TOS novel: Ghost-Walker)
Personal logs often were used in the course of an investigation of a person. In 2268, Commander Spock reviewed Captain Kirk's personal log after it appeared that Captain Kirk was behaving strangely. Spock realized that after the mission to Midgwins that Kirk had stopped making entries to his personal log, and that the warm tone of voice found in Kirk's personal log was missing from the official Captain's log.
