Bookplate is a printed label pasted in a book as a mark of ownership. The label is sometimes called ex libris, which means from the library in Latin. Most bookplates are made of paper, but vellum, leather, and other materials are sometimes used. Early bookplates were engraved by hand. Modern bookplates are produced by mechanical processes (see Engraving). A simple label printed with the owner's name and address makes a satisfactory, inexpensive bookplate.
