Not true. Just something he said. Which was incorrect as were most things he said.
noam chomsky did a 3 hours cspan book tv interview about 10 years ago.
the book tv host says "...you have published 65 political books, and 33 linguistic books from a total of 60 different publishers. we have been doing book shows here for many many years, and i have never heard of anybody publishing 98 books."
so the "market" which you bow before, has said there is extraordinary demand for noam chomsky books and what he has to say.
