Title

¬The emerging technology : an overview of the impact of CD-ROM on offline services

Source

Journal of educational media and library sciences. 30(1993) no.2, S.122-138

Year

1993

Abstract

Examines the possibility of CD-ROM databases supplanting traditional online database searching methods as a result of greater cost effectiveness, speed and ease of use. Concludes that CD-ROMs will not replace online databases in the near future because of the greater variety and amount of information which is available online. Points to the lack of standardization running through many aspects of CD-ROM technology
