Chapter 1 - Footnote 3
This reference originally appeared at Wikipedia circa 2013, but may have been removed. I have linked to the original reference using archive.org and provided additional references below:
The original edition published by Macmillan in 1966 sold about 8800 copies and sales were picking up in 1968 when they “ran out of stock,” as they told me (but in 1974, when I went after them with a lawyer, they told me that they had destroyed the plates in 1968). They lied to me for six years, telling me that they would re-print when they got 2000 orders, which could never happen because they told anyone who asked that it was out of print and would not be reprinted. They denied this until I sent them Xerox copies of such replies to libraries, at which they told me it was a clerk’s error. In other words they lied to me but prevented me from regaining the publication rights by doing so. [Rights revert back to the copyright holder if the book is out of print, but not if the book is simply out of stock.]…Powerful influences in this country want me, or at least my work, suppressed.
