The site, Journey to Forever, has a Small Farms Library of (mostly) old books useful to small-scale farmers and homesteaders. Books like this one: Handy Farm Devices and How to Make Them. My favorites were the Food Cooler and Filter for Cistern Water in the chapter called In and Around the House (part II).
Urban homesteading is a way to be self-sufficient and independent while still living in town by: growing your own food, using alternative energy sources, reducing waste, living simply and doing it yourself.
