"The book is a medium that requires no visual display, other than to be read, and the active mental participation of the reader. The book imposes no information system, but the printed image and the word; it is a complete entity in which both public and private documents are reproduced. The book is a collection of photographs, writing, and ideas- it is a product of thought and of imagination. It is a result of concrete activities, and serves to document, and to offer information as the means and the material of art. It is considered an object of study and of testimony and does not appear esoteric or unreal, but fits into the daily communications system without any aesthetic or artistic pretension. It is only another space.. and can therefore be considered a work of art." --back cover. Second edition of 800 copies. Originally published in 1972. -- t.p. verso.
