Artists' books have been described as the "quintessential 20th century art form" (Drucker, Johanna. The Century of Artists Books. New York: Granary Books, 1994), and indeed, though there were many predecessors to the contemporary artist's book, the form was really born in the late '50s and early '60s. The collection at the Architecture and Allied Arts Library, which is supported and extended by artists' books in Knight Library's Special Collections, spans the history of these works of art in book form from 1957 to books by artists today with special emphasis on artists working in the Pacific Northwest. The collection is represented here with images and data describing bindng style, structure type, technique, literary style and materials.
