"Emmett Williams, as one of the original practitioners of concrete poetry, has been in a unique position to observe the development of the movement since its beginnings, and the selection in this volume therefore reflects a view of this evolution from within the movement rather than from a distance. However it is far too soon to regard any anthology of Concrete Poetry as being definitive since the movement is extremely active and major new works have yet to appear in this most interesting of current poetry movements." -- from interior flap.
