Communication: The Essence of Science provides information pertinent to the fundamental aspects of scientific communication. This book focuses on those information-exchange activities that take place mainly among scientists actively involved on the research front. Organized into five chapters, this book begins with an overview of the psychologists' description of the communication structure of science. This text then examines the relationship among spanning, connecting, and integrating the various streams of activities involved in the production of information. Other chapters consider some of the main republication media and suggest ways that may be used in the librarian's effort to provide effective information services to scientists. This book discusses as well the significance of scientific articles to the scientific community. The final chapter deals with the significant role of librarians as a social scientist. This book is a valuable resource for psychologists, social psychologists, librarians, social scientists, sociologists, engineers, teachers, and students.
