Recent developments in Derwent publications' patent information services: A review with some predictions for the future

Michael D. Dixon and Charles Oppenheim

World Patent Information, 1982, vol. 4, issue 2, 60-65

Abstract: Recent developments in Derwent's patent information services are described. Electrical Patents Index is a new and sophisticated information retrieval service covering subjects of interest to the electrical and electronics industries. Patents Abstracts on Microfiche is a forthcoming service for simple and inexpensive searches through Derwent's entire collection of abstracts. Developments in Derwent's chemical coding system are briefly described, and major developments in its online data-bases are also described. The paper finishes with some speculations about the impact of new technology, particularly in regard to the mass storage of graphics and in-house spinning of mini-data-bases.
