Title
Will today's databases survive : a question of value
Source
Information today. 13(1996) no.1, S.21-23
Year
1996
Abstract
Discusses the evolution of online databases during the 1990s considering the effect of cheap information accessed through the Internet. InfoSeek includes Associated Press Online, Reuters Business Report, Commerce Business Daily and Cambridge Scientific Abstracts for a basic 9.95 dollars per month. PR Newswire offers an automated faxback system of press releases at no charge to the caller. CD-ROM directories are making online access almost obsolete. With greater numbers of sophisticated electronic competitors, survival can only be achieved through high quality access, accuracy and added value
