The SAS book is a good place to start. Like I said ( or tried to), each book gives a different slant or emphasis to gear lists ( the famous10 essentials) methodology, philosophy ( go light, go native, go electronic, go away please). After a few books you realise there are a finite number of topics and want to rip the bowdrill illustrations to pieces. Thats when the subtle hint of greasing the bowdrill in book number three pops up. Doug's reference on site is pretty comprehensive. chances are any other title has been read by a forum member. Just ask before buying ;O)
