While there are hundreds of agile titles available, these are the volumes that have an honored place in my personal library, and the ones I recommend to agilists hoping to begin their agile apprenticeship or enhance their skills. I tried to cover a wide range of topics, from software development and testing to agile scaling and leadership. Many of these titles are cited by Project Management Institute (PMI) as the basis for its PMI-ACP exam¹ and are acknowledged classics in the agile canon.
