Learn how to buy, dry, store and mill timber. This text explains which species are good for which jobs and how to design joints that accommodate wood's seasonal swelling and shrinking.
This wasn't quite what I was expecting as it is very much geared towards commercial timber yards, mills etc. rather than small scale and/or private means. This aside, it was very informative and I assume its at least fairly accurate although I suspect it may be a little out of date in places (of course, given how little I know about these things, it could still be absolutely spot on!).
