This volume of original research contributes to the renewal of interest in Marshall McLuhan and his work. In Section One, four chapters provide a general discussion of McLuhan's work. The chapters in the second section present the reactions of five media professionals to McLuhan and his work. The third section explores topics that go to the heart of McLuhan's theories: the linearity of written communication, perception as it is reflected in artistic expression, and media semiotics. Section Four emphasizes the humanistic basis of McLuhan's thought and its applications. Chapters in the fifth section cover the sector of scholarship for which McLuhan is best known. Chapters in the final section examine his work in light of theory and research on the new media of the past two decades.
