Ex Libris – Robert Andrew Allison – Vincet Veritas (Truth will Prevail)

An Ex Libris from ex librīs (Latin for 'from the books (or library)'), also known as a bookplate (or book-plate, as it was commonly styled until the early 20th century), is a printed or decorative label pasted into a book, often on the front endpaper, to indicate ownership. Simple typographical bookplates are termed "book labels".

Bookplates often bear a motif relating to the book's owner, such as a coat-of-arms, crest, badge, motto, or a design commissioned from an artist or designer. The name of the owner usually follows an inscription such as "from the books of..." or "from the library of...", or in Latin, "ex libris". Bookplates are important evidence for the provenance of books.
