This celebration of media prophet Marshall McLuhan takes what the editors (who also produced a CD-ROM titled Understanding McLuhan) call a ``mosaic'' approach, a nonlinear concatenation of images and bits and pieces of text that ``inexorably echo, circle, and shift into one another.'' One feels Beneditti and DeHart have somehow missed the point in trying to force this nonlinear presentation into book form--print media being, according to McLuhan himself, the quintessential linear mode for passing information. The result thus seems less a surprising kind of new- media presentation than a frustrating kind of book, stagnant and redundant. It offers a free association of media-tized images (a nuclear mushroom cloud juxtaposed with a photograph of Dr. Ruth); biographical tidbits; quotes from McLuhan that replay ad nauseam such central themes as the global village and the loss of identity suffered by Mass Media Man and Woman; and tributes from his admirers. The medium isn't the message here.
