it realy does depend on where you want to go with it, I started from a more militry back ground so i read a lot of the Lofty wiseman stuff, ery good but very hard core, there is Ray mears stuff which is the other extreme were he is a back woods man rather than a survivalist, what i would suggest is to start some where say like foraging in the hedgerows and then read up on free food by maybe and such like and then slowly progress from there
