Title

Multimedia and CD-ROM Directory 1998

Source

Information today. 15(1998) no.8, S.45

Year

1998

Abstract

Traces double change in ownership of the Multimedia and CD-ROM Directory, now over 10 years old and reviews the 1998 edition under the imprint Waterlow New Media Information. Also describes Waterlows new specialised tool, the DVD Directory. The Gale Directory of Databases and Bowker's World Databases might be suitable alternatives to certain users but the Waterlow product should be the first choice for libraries seeking a source of directory information related to CD-ROM
