If you want to understand more about communalism, texts of Murray Bookchin and Janet Biehl or websites like those of New Compass and Institute for Social Ecology would be the best way to go. Communalism is quite close to social anarchism but less interested in individualist or anarchosyndicalist thinking. Unfortunately, communalism will be often confused too much with the democratic confederalism of Abdullah Öcalan but that's just not the same thing, even when Öcalan has been quite influenced by the communalist ideas of Murray Bookchin.
