Everything you can find in your local library
Bill Houghton, rainin' here this evenin'
>I think it's foolish to spend money on books when your tax dollars have purchased a whole library, just for you. You may ultimately want one or more to keep, but best that you make this selection yourself after reading through them, trying out what you learn, going back to read them with the knowledge thus gained, etc. So get yourself to your local library and raid the shelves. Read everything, absorb, and go from there.
That said, some of the classics are pretty hard to beat, and often not available in the library. I like "Planecraft," an inexpensive ($10 or so) book available from Woodcraft.com. The trouble with this book, though, is precisely that it's about planes only (well, with some wandering into vises; and counting spokeshaves as planes); left out of the discussion are the broad capabilities of chisels, drawknives, etc.
Hand woodworking is ultimately very simple: you cut the wood with full respect for the vagaries of a material that cuts well in one direction and terribly in the other, and varies from board to board, much less species to species, and sometimes from inch to inch, fasten it together, and there you are. But this is like saying that playing trombone is simple: you just blow in one end and move the slidey thing back and forth. Getting from there to Fred (or Jac) Assunto is the trick, and it's important to remember the old getting-to-Carnegie-Hall punchline - "practice, man, practice" - and its corollary - "patience, man, patience." Start with simple projects and woods before tackling a colonial secretary-on-chest from jarrah or some other exotic.
