THE ECONOMICS OF WRITING TECHNICAL BOOKS

Summary from the TLDR Web Dev newsletter

Technical authors can make a decent income from their books, but they should not write them solely for monetary reasons. The amount of money earned varies depending on the distribution channel, with self-publishing platforms like Gumroad and Leanpub offering higher royalties than traditional publishers. Technical books can generate passive income over a long period, with some titles remaining relevant for decades. However, most technical books sell less than 5,000 copies per year.
