From coller, French for “to paste,” a collage is a composition using pieces of paper, cloth, etc., glued onto a surface. The glued materials refer to something in the world but also act as elements of the composition. When they are juxtaposed, the elements generate new meanings. Modern collage traces its roots to the Cubist artists Georges Braque and Pablo Picasso. These books feature collage techniques in their use of images and letters cut out from print material and pasted onto the covers.
