'logbook' originates from the combination of 'log' and 'book', where 'log' referred to a record of a ship's speed and progress.

'log' was used in the 17th century to refer to a record of a ship's speed, and 'logbook' became a common term in the 18th century.

Initially, it meant a record of a ship's journey, but now it can refer to any detailed record of events.
