This is the second of four reports representing an effort to develop a system of indicators of scientific technical information. This particular report is concerned with the data analyses which led to the system of statistical indicators described in the first report. It includes a discussion of the overall framework upon which the study was based as well as of the analysis and mathematical models used to generate the indicators. It is organized into sections covering the major functions involved in the communication of scientific and technical information--research and information generation, trends in publishing and technical information, acquisition and storage of information, organization and control, identification and physical access, assimilation and use of information, and total cost of communicating scientific and technical information. The report is heavily illustrated with graphs and charts. The background and trends for this data are discussed in the first volume (IR 004 374). (Author/DAG)
