A guest book can also be referred to as a visitor's book, an attendance register, a sign-in sheet, or a reception book. Some may call it a memorial book where visitors write down their condolences in honor of a deceased loved one. It can also be referred to as a message book or a comment book, especially for events where the organizer wants to collect feedback from guests. The word can also be customized depending on the occasion, such as a wedding guest book, a funeral guest book, or a vacation rental guest book. Ultimately, whatever the name, the purpose of a guest book remains the same: to record and remember those who attend an event.
