This paper presents an extensive, critical review of Eleanor Gibson and Harry Levin's "The Psychology of Reading." Treating the book as an attempt at comprehensive integration of the literature on the reading process, the reviewers look for a theoretical account that will bind findings together, for a critical examination of the research literature, and for an evaluation of practical consequences of the research efforts mounted over past years. After reviewing the scope of the Gibson and Levin book, the paper compares the work with its predecessors. Specific topics covered in the book are examined in detail, on an almost chapter-by-chapter basis. Concluding that other efforts to treat the psychology of reading have more nearly achieved their purposes than have Gibson and Levin, the reviewers go on to outline both what they feel we have learned about the topic and the fundamental questions remaining to be answered.
