Artists' books are works of art realized in the form of a book. They are often published in small editions, though sometimes they are produced as one-of-a-kind objects referred to as "uniques".

Artists' books have employed a wide range of forms, including scrolls, fold-outs, concertinas or loose items contained in a box as well as bound printed sheet. Artists have been active in printing and book production for centuries, but the artist's book is primarily a late 20th century form.

"Artists' books are books or book-like objects over the final appearance of which an artist has had a high degree of control; where the book is intended as a work of art in itself." Stephen Bury

Whilst artists have been involved in the production of books in Europe since the early medieval period (such as the Book of Kells and the Très Riches Heures du Duc de Berry), most writers on the subject cite the English visionary artist and poet William Blake (1757–1827) as the earliest direct antecedent

Books such as Songs of Innocence and of Experience were written, illustrated, printed, coloured and bound by Blake and his wife Catherine, and the merging of handwritten texts and images created intensely vivid, hermetic works without any obvious precedents. These works would set the tone for later artists' books, connecting self-publishing and self-distribution with the integration of text, image and form. All of these factors have remained key concepts in artists' books up to the present day.
