Simon Cutts, publisher and poet, writes in an introduction, "It is by now difficult to substantiate any single definition of a book as made by an artist, and indeed this very issue may have been surpassed...These new books attempt to synthasise text, image, material, method of production and context into a unified single work. When this succeeds, the book functions as a primary form." -- Source of annotation: Marvin or Ruth Sackner.
