I think this a great short piece on "What are Artists' Books?":
Artists' books is the broad term used to describe books, unique or multiple, that have been made or conceived by artists. There are fine artists who make books and book artists who produce work exclusively in that medium, as well as illustrators, typographers, writers, poets, book binders, printers and many others who work collaboratively or alone to produce artists' books. Many artists' books are self-published, or are produced by small presses or by artists' groups or collectives, usually in limited editions."
