Register books (often called guest books or funeral guest register books) are large bound books placed at the entrance of a funeral, memorial or visitation service so attendees can sign in and leave messages, comments, or simply record their attendance. This allows the family and service provider to document who attended (helpful for thanks/acknowledgements later). Offers a keepsake for the family — guest names, signatures and possibly messages that become a memory book. Often matches the visual theme of the service (cover design, color, motif) for a cohesive presentation.
