Here is a report that pulls together information on "209 civic tech organizations that cluster around pockets of activity such as tools that improve government data utility, community organizing platforms and online neighborhood forums." : knightfoundation.org/blogs/knightblog/2013/12/4/pulling-back-curtain-civic-tech.
