Abstract
Reviews 4 CD-ROM encyclopedias: Encyclopaedia Britannica CD 98 Multimedia Edition; Compton's Interactive Encyclopedia 1998; Microsoft Encarta 98 Encyclopedia; and Grolier Multimedia Encyclopedia 1998. Each of the 4 titles has its audience and while no single CD-ROM encyclopedia is perfect, some perform better at specific tasks than others. Britannica has the content with its academic, rich textual information. Compton's is richest in variety and games to help children learn and has a perticularly good interactive atlas. Encarta is beautiful designed and would be the choice for adolescents and young adults. Grolier is more affordable than the other titles and though inferior in images to Encarta has a greater depth of content
