Article: Jeff Jarvis on the Age of Print and the Age of the Internet (REVIEW ESSAY) - The American journalist Jeff Jarvis (born in 1954) has published the accessible new 2023 book The Gutenberg Parenthesis: The age of Print and Its Lessons for the Age of the Internet (Bloomsbury Academic).

Ong (1912-2003; Ph.D. in English, Harvard University, 1955).
