THE EVOLUTION OF INFORMATION SOURCES AND THE USE OF INFORMATION‐TECHNOLOGY IN AGRICULTURAL ECONOMICS
回顾了过去25年农业经济学领域文献、统计和市场信息源的发展，特别是计算机应用后的变化，讨论了主要文献源和用户教育需求。
The paper reviews developments in bibliograhical, statistical and market information sources over the last 25 years, particularly since the application of the computer to information processing and dissemination. It concentrates on bibliographical sources: the evolution of WAERSA from a quarterly abstract journal to a monthly one, now also accessible on‐line, as well as discussing some of the other major bibliographical sources, notably the AGECON file on USDA's AGRICOLA (formerly the Bibliography of Agricultural Economics), FAO's AGRINDEX, a title‐only service available as a monthly journal and on‐line, the Bibliography on Agricultural Marketing from FAO's marketing division, and the information service provided by ESCA. Different methods of ‘packaging’ information are also mentioned, including regular profiles on particular topics (SDI), ‘state‐of‐the‐arts’ reviews, and ‘start’ reports. The paucity of adequate source guides specially tailored to the needs of agricultural economists is discussed. Finally, the availability of farming and market information through videotex is described. A plea is made for greater co‐operation between providers and users of information, better knowledge of and guides to sources, and for user education.
