This report of a United Nations Educational, Scientific, and Cultural Organization (UNESCO) pilot project, which was carried out during 1982-84 in Khartoum (Sudan) to develop a vehicle for providing access to information on research in progress, describes: (1) the study that led to the conclusion that a national register of research projects was required in Sudan; (2) the collection of information for this register; (3) the procedures set out for its processing, production, and dissemination; and (4) the results of the study and suggestions for its future development. The register produced by this project is a single 552-page volume in English which lists 1,269 projects reported by some 300 sources both in the Sudan and outside. It is designed for use by researchers, research managers, and policymakers who require information on what, where, and how research is being organized and who is implementing it. The information in the register is intended to constitute a database for user referral to sources of scientific expertise; provide news of publications about to appear; and indicate potential users for scientific and technological information services. Fourteen annexes include questionnaires and other materials relevant to the study. A list of abbreviations, a 14-item bibliography, and a subject index are also provided. (CGD)
