Even though some have said that Churchill has been published only in "the vanity press," it appears that he has, in fact, mostly been published by non-peer-reviewed publishers. It is clear with even the most cursory inspections of the various backlists, that with the possible exception of Routledge, Churchill's publishers cannot be considered academic or scholarly publishers, but rather radical leftist agenda-driven publishers.

The format is:

Pacifism As Pathology: Reflections on the Role of Armed Struggle in North America (Ward Churchill, Co-Author)
Arbeiter Ring
www.arbeiterring.com [ed. note: link returned "server not found" at time of this writing]
[note: info provided from MSN Search cached page] "Arbeiter Ring ("Worker's Circle") borrows its name from the radical Jewish fraternal organization. A century ago, socialist and anarchist locals of the Arbeiter Ring were active on the political and cultural level in Winnipeg, including participating in the 1919 Winnipeg General Strike and organizing Emma Goldman's visits to the city. ARP is not-for-profit (likely a redundancy in Canadian book publishing these days), and organized as a workers' collective. Our understanding of workplace democracy is heavily informed by "participatory economics" (parecon), a model developed by Arbeiter Ring author Michael Albert and Robin Hahnel. Parecon is a type of economy proposed as an alternative to contemporary capitalism; its underlying values are equity, solidarity, diversity, and participatory self management."
