What does logbook mean?
A logbook is a book in which events, observations, or other information are recorded systematically. Its best-known use is as the official record kept on a ship, documenting matters such as the vessel's position, weather, course, cargo, and notable incidents. The word can also describe any organized record of activities, as in a research logbook or a pilot's logbook. In general use, a logbook is usually more detailed and orderly than a casual diary: its purpose is to preserve a reliable account for later reference, compliance, or analysis. The term is formal but not especially technical outside maritime, aviation, military, and scientific settings. A logbook may be kept in paper or electronic form, and entries are commonly organized by date or journey. Its importance lies in the way it turns individual observations and actions into a durable institutional record.

Where does logbook come from?
The word is a compound of log and book, with log meaning a record or the written record of events. The recording sense of log developed in English through the practice of keeping a ship's log, while the compound logbook became established in the 19th century. The word is related to logger and logging, which share the same historical association with recording and keeping logs.
How logbook is actually used
The word is formal and factual. In maritime contexts, it usually means the official record required aboard a vessel; in other contexts, it suggests a regular written record of events or observations.
