I picked this up one summer day to read at the beach. Realised there was a lot of info and it was researched and well written for the weekend DIYer, also good for Scouts etc. A really good referance book that every library or bird enthusieists should have. The drawings are done quite well, helps you buy materials to save money. The only thing missing is details of the required nails or screws, but that's not too much of a problem.
