I hope you wrote that book more for personal pleasure and fulfillment than monetary gain. Over 32 years, would you have to be a best seller given the price of your book on Amazon (without counting the free audiobook you offer if someone starts a trial) to be making a minimum wage.

If you did that for passion and the book is good, it will definitely have a bigger impact if people can read your stories without having to go through Jeff or a bookstore (many English books are very hard to acquire outside of the US).

So, rejoice in the fact that someone thought your book was worth making available for the few who even know how to use these kind of online libraries (most people in the world don't). Bitterness on loss of revenue is definitely not worth it, especially after having put 32 years of life into it.

Unfortunately I don't really care about 60s US tech "scene" but the cover seems nice.
