Bill Mollison, the co-founder of Permaculture
This downloadable PDF (which opens great in any e-book reader) is a collection of "pamphlets" dealing with many aspects of Permaculture... all from Bill Mollison, the founder of Permaculture. Well, to be honest, it is not quite from him. It is the transcript of a Permaculture Design Course he was teaching in 1981 in New Hampshire. The good folks from Barking Frogs Permaculture taped the course and then typed it all. On top of that, they made it a public resource...free public domain! This compliation of all 15 pamphlets is free to anyone who wants it. A fantastic resource.
