Abstract

Highlights the need for standards for the CD-ROM industry to ensure compatibility and to increase the economies of scale. CD-ROM, as a unique publishing medium, has standards mainly at 3 levels: the physical level, concerning the physical and recording characteristics of the medium; the logical level, concerning the nature of files, directories, and volume descriptors; and the application level, concerning retrieval software, graphics, compression, and encryption. Lists some specific CD-ROM standards (Red book, extended red book, Yellow book) with brief descriptions and the way in which they are related and linked to each other and to other optical disc applications; such as audio CD, CD-I and CD-ROM XA. Concludes that CD-ROM technology brings database services within the reach of information centres, especially in developing countries. Positive trends towards standardization in this technology should help to reduce the technical hurdles
