Lean Book Publishing is a new approach that focuses on publishing books readers want to buy and read. Each year over 2 million new books are published but the average book is read only 250 times, resulting in unhappy authors and wasted resources. Lean Book Publishing aims to increase book sales and reader satisfaction by publishing engaging content for readers, thereby improving the book industry for both authors and readers. Their goal is to raise total book sales by 10% and average reader satisfaction by 25% by 2020.
