Bioshelter Market Garden by Darrell Frey
Urban Homesteading by Rachel Kaplan with K. Ruby Blume
Growing Older by Joan Dye Gussow
There has been a lot of interesting books written less from a permaculture perspective and in more of a reporting on 'new agriculture' way as well "The Town That Food Saved," and books that touch on broader food security issues such as "The Last Fish Tale," not to mention some fun memoirs like "Farm City" and "Quarter-Acre farm."
I read Holy Shit: Managing Manure To Save Mankind by Gene Logsdon its an amazing book. The whole thing is just sort of amazing, I want to buy a copy just to leave on my coffee table, since really its a small and attractive volume. His other book Small Scale Grain Raising is also a really great read.
