When Citizens Decide, from Oxford University Press, is probably the definitive book on citizens' assemblies. They're quite rare, and they tend to come about for non-partisan reasons, or when some political party gets the idea—as Dalton McGuinty did, or Gordon Campbell did, or a group in the Netherlands did—that we should do something about this. Apart from that, they just don't happen. You might choose to make it happen, but they don't come out of the blue. Most parties do not see that kind of study as being in their interest. Most parties want electoral reform to be their electoral reform to help them. It's just the way the world is.
