A logbook is a record-keeping tool used to document activities, events, or observations over time. It is commonly used in various fields, such as aviation, maritime, and scientific research, to ensure accurate tracking of important information. Logbooks can help maintain safety, compliance, and accountability by providing a clear history of actions taken. Typically, a logbook includes details like dates, times, locations, and descriptions of events. For example, a ship might use a logbook to record its journey, while a scientist may document experiments and results. This organized approach aids in reviewing past activities and making informed decisions.
