Can a profit be made publishing thin books for narrow audiences? Can they be inexpensive too?
The size of the book drives two important outcomes I've written about before, in my Thin Book Movement article: first, the book was cheap enough that it was easy to buy on impulse, and it was an obvious value choice over other books on the market that cost 4x to 8x as much.
