Bayard dedicated the book, which developed from her doctoral thesis, to Ruth and Marvin Sackner. In the acknowledgments she states, "I would like to express my gratitude ...especially to Marvin Sackner for generously granting me unlimited access to his marvellous collection of concrete and post-modern artefacts. Without such direct, visual, and hands-on contact with concrete and deconstructed items, I would have known them only abstractly."Bayard's book is heavily oriented to criticism and theory of concrete poetry with particular attention to the work of bp Nichol. -- Source of annotation: Marvin or Ruth Sackner.
