This is a pretty interesting book that mostly tells a bunch of stories about what it calls "momentum-driven organizing" - basically large strategic nonviolent protests. This is laid out as separate from "structure-based" organizing, in the tradition of unions, community organizations, etc. The book argues that both of these traditions are necessary to create lasting and meaningful social change, and can complement or detract from each other depending on a variety of factors.

It lays out a few tenets for successful campaigns and goes through several case studies, including Otpor, ACT UP, the SCLC, and others.

I found this book informative and inspirational - it really helped focus my thinking about the limited amount of activism I have done, and will continue to shape my thinking going into the future.
