Nineteen articles by Louis Shores are presented in this volume. These develop the idea of the "generic book" as being the sum total of man's communication possibilities and trace the crusade for media unity which has culminated in the acceptance of the concept of instructional materials, encompassing the narrower concepts of both libraries and audiovisual aids, as the most useful approach to learning materials. The first part of the volume is comprised of six articles dealing with the generic book; following this, the second major section offers five essays which focus upon the materials center. Part III treats the media college and in the concluding portion, five articles which cover various aspects of media education are presented. An appendix listing some landmarks along the way to media unity and a selected bibliography are also included. (LB)
