New Complete Smallholding by John Seymour
If you only get one book about smallholding and self sufficiency then this has to be that book. Absolutely all aspects are covered and normally in enough detail to give a beginner plenty of information and guidance, I can easily see that this will also become a reference book in future even after we have gained more experience.
Practical Self Sufficiency by Dick and James Strawbridge
A great reference book packed with interesting information and intriguing DIY projects under a variety of headings such as The HOME, THE PLOT, TRADITIONAL KNOWLEDGE and much more. The chapter dealing with renewable energy was particularly interesting and gave me a number of ideas for the future.
