See a link referencing The Gutenberg Galaxy (a Catholic's 1962 view of literacy)
in a Log24 post yesterday suggested by a New York Times obituary.
A different obituary this evening in that newspaper describes a Jew's 1979 view
of literacy. See "Elizabeth Eisenstein, Historian of Movable Type, Dies at 92."
Related material — McLuhan in Eisenstein's The Printing Press as an Agent
of Change , Cambridge University Press, 1979.
Eisenstein reportedly died on January 31, 2016. Synchronologists may
consult some media-related material reposted here on that date —
Fittingly, the Times concludes Eisenstein's obituary as follows —
"This article will be set in 8.7 point Imperial and printed on
one of several presses, including the Goss Colorliner."
For a perhaps more interesting printing press related to change,
see Despedida in this journal.
