The papers in this collection, which explore selected aspects of scientific and engineering communication, are the results of a study designed to learn more about the relationships between information resources and scientific productivity. The first three sections contain three key papers related to a conference sponsored by the Council of Library Resources (CLR) that enabled a group of scientists and academic leaders to consider the general topic. A background paper, the transactions of the conference, and a summary statement, taken together, open up many of the pertinent issues and provided a base for future action. Three additional papers, triggered by the conference discussion, were commissioned by CLR: (1) "The Users and Uses of Scientific Information Resources: Recommendations for Study (Helen H. Gee); (2) "Library Resources and Research Productivity in Science and Engineering: Report of a Pilot Study" (Nancy Van House); and (3) "In Preparation: A Comparison of Costs of Library and Information Services in Academic and Industrial Libraries That Support Science and Engineering" (David Penniman and Jay Lucker). Three appendices contain the questionnaire and cover letter for a survey of selected Association of Research Libraries member libraries; statistics on library materials prices; and a table showing the correlations of science library resources with productivity measures by year from 1985 through 1989.
