Celebrated in its first edition as an indispensable guide, Secondary Research has been revised to provide the latest information on computer-based storage-and-retrieval systems. This volume was originally designed to help locate and obtain secondary sources, as well as evaluate and integrate the information from the various sources in order to answer specific research questions. The new edition features expanded coverage of computer-based information, including a new chapter on CD-Rom products and updated coverage of on-line information search services. In addition, this volume includes beneficial material on how to conduct secondary analysis, specific sources such as commercial and government sources, including the 1990 U. S. Census, and examples of information searches. A must-read for anyone--professionals, researchers, professors, and students--in the areas of research methods, evaluation, management, psychology, and sociology.
