My question is this: Can you point me to a list of significant (especially book-length) works on (a) anarchism and law, and (b) anarchism and psychology? I've written several short things on aspects of this, and am looking to see what I might have missed that might tie the whole thing up more systematically.
You might want to start with a bibliography, or, even better, an annotated bibliography. These are listings of other book-length works (often including theses and journal articles as well); annotated bibliographies include descriptions and indexes to help you find what you're looking for. Some bibliographies that might be good starters include:
"A Comprehensive Anarchist Bibliography" on the Web
Anarchist Thinkers and Thought: An Annotated Bibliography
Nursey-Bray, Paul
Greenwood Press, ISBN: 0-313-27592-0
I also came across these books during my search that might be of use:
Brewster, H. B. (1887). The Theories of Anarchy and of Law.
A Midnight Debate. London, Edinburgh: Williams and Norgate.
Holterman, T., and Maarseveen, H. Th. J. F. van. (1984). Law and anarchism. Montreal, Quebec : Black Rose Books.
Morland, David. (1997) Demanding the impossible? : human nature and politics in nineteenth-century social anarchism. London [England] ; Washington, D.C. : Cassell.
J. Roland Pennock and John W. Chapman. (1978) Anarchism. New York: New York University Press. (This is from the Nomos series of law theory books - a tip from another Radical Reference librarian recommended this one.)
