If you want to make your book a best seller, somehow get it banned....
In the 1960s, my community in Ohio banned Henry Miller's 'Tropic of Cancer'.
This was before the internet so I had to call on friends in seversl different states until I found one who could purchase the book. I finally got the book and read it. It wasn't that good, but I just couldn't stand someone telling me what I could or couldn't read. It was a hard bound copy, and it is one of the few books I actually lost. I think I loaned it to somebody and they never returned it. If someone with a pristine mind thinks 'Huckleberry Finn' or 'Catcher in the Rye' is racist or obscene, ask them to read Henry Miller. They may go into a catotonic state.
