Here is the jacket summary on the Ginko Press site, looks like a site worth noting: (thanks for the link Josh)
Until now no book has explored the full expanse of Marshall McLuhan’s thinking or writing. The Book of Probes is an exciting new publication that brings together for the first time a collection of his most prescient aphorisms and excerpts from his prolific life’s work. It is a revolutionary book that distills the wisdom and wit of the brilliant man who was first to understand and articulate thoughts on media, privacy invasion, the information environment, and much more. McLuhan’s bold perceptions, such as ”obsolescence is the moment of superabundance” he called ‘probes’ and they gleam today like hidden gems in his many books, in more than 200 speeches, in his classes (especially the Monday Night Seminars), and most of all in the nearly 700 shorter writings that he published between 1945 and 1980.
Over the past couple of years Eric McLuhan, Marshall McLuhan’s son, and William Kuhns have combed through all of his writings to extract and compile a complete collection of ‘probes’ which has become The Book of Probes.
Not only are these one hundred percent McLuhan’s own words, these are McLuhan’s finest words and, incredibly, most ‘probes’ are so fresh they will be new to even the most avid McLuhan readers and enthusiasts. The Book of Probes opens a new portal to McLuhan’s mind and sets a new precedent as to how we will interpret and appreciate McLuhan in the future. Readers will marvel at how the consistency, the clarity of concept, and the abundant wealth of observations, some made twenty or thirty years apart, dovetail to form a whole.
Art Director and Designer David Carson presents McLuhan’s work with refreshing new visual insight, and in doing so has added his indelible mark to a body of work that is destined to be recommissioned and reinterpreted by countless generations to come.
With commentaries by Eric McLuhan and Terrence Gordon, author of Marshall McLuhan Escape into Understanding.
