A bookplate is a decorative label or sticker that is placed inside the cover of a book to indicate ownership. Typically, it features the owner's name and may include artistic designs or illustrations. Bookplates serve both a practical purpose, helping to identify who owns the book, and an aesthetic one, adding a personal touch to the book's interior. Historically, bookplates have been used by collectors and libraries since the 15th century. They can be made from various materials, including paper and adhesive vinyl. Some bookplates are designed by famous artists, making them collectible items themselves, much like ex-libris labels that denote ownership.
