This final report of the Targeted Research and Development Program in Reading, Project 2, Literature Search, constitutes the results of a massive search of literature in the area of reading to find and synthesize all of the literature pertaining to models of reading development and process. General areas of models considered are language development and reading, learning to read, and the reading process. The first five sections describe the background and development of the search procedures, outline areas from which models are drawn and describe a number of models, and seek to synthesize the information obtained. The final sections contain 16 separate papers in the three general areas defined. Bibliographies follow each of the papers. (MS)
