One year ago, at the Agile 2010 conference, I came up with the idea to publish a Top 100 Agile Books. Like many of my other top 100 lists it was a great success (in terms of blog traffic).
This year I am not at the Agile 2011 conference (for various reasons, both good and bad). But nevertheless, I decided to publish a new edition of the Top 100 Agile Books, especially for my friends at Agile 2011 who are enjoying a great conference without me.
This list is based on quality (averate ratings) and quantity (number of ratings), both on Amazon.com and GoodReads.com. The age of the books also played a minor factor in the calculations. (Older books should keep acquiring new ratings, or else they drop in the list.)
