It’s a rather long list.

Top 100 Agile Books (Edition 2013) – by Jurgen Appelo

This ranking of 100 best agile books is the average of five different rankings: the number of Amazon reviews, the number of GoodReads reviews, the average Amazon rating, the average GoodReads rating, and the number of days since first publication. That means this list shows you a mix of the most popular, best rated, and (relatively) newest books in this category.
