While I was quite familiar with some of the examples in the book, based on the authors' previous publications (and resources on the Public Science Project website), the book did provide me with a better understanding of all the steps (and their challenges and joys) of CPAR projects, which aren't that easy to get from articles alone. Also,I really appreciated the "Methodological release points" parts, as well as the vulnerable disclosures of mistakes/mishaps along the way and new resources on (C)PAR projects. As someone who's trying to do this kind of work in an environment where people doubt the scientific value and robustness of (C)PAR, I found the book useful and encouraging.
