Creator: Peter Armstrong is the Co-founder of Leanpub and Ruboss. He is also the author of several books including Lean Publishing.
Purpose: Books and writing are changing. And given most books are written in isolation or in stealth it is easy to write a book that nobody wants to buy/read. The Lean Publishing Manifesto suggests a way around this.
Manifesto (highlights)
Lean Publishing is the act of self-publishing a book while you are writing it, evolving the book with feedback from your readers and finishing a first draft before using the traditional publishing workflow, with or without a publisher.
In short: Lean Publishing is the act of self-publishing an in-progress book.
