A Visitor Book is a record used by organizations, businesses, or events to log the details of individuals who visit their premises. It typically includes information such as the visitor's name, date of visit, time of arrival and departure, and purpose of the visit. This helps maintain security and track attendance. Visitor books can be found in various places, including museums, hotels, and offices. They serve as a useful tool for managing visitor flow and can also provide valuable insights for improving services or facilities. Some modern versions may even be digital, allowing for easier data management.
