Loomis, Mildred J. Decentralism ; Where It Came from; Where Is It Going? York, PA: School of Living Press, 1980. Link to Google Books edition.
Loomis documents the ideas and experiments of American decentralists including Arthur Morgan, Henry George, Benjamin Tucker, Paul Goodman, and Ralph Borsodi. All shared a common belief in restoring community self-reliance and bringing economic and social activities back to a human scale. Their experiments played a pivotal role in introducing and supporting organic agriculture, consumer rights, worker-owned cooperatives, community land trusts, alternative education, the ecological use of resources, consensus decision making, and alternative currency and nonexploitive banking.
