I read lots of these, but I don't tend to want to own them. I found Ursula Le Guin's "Steering the Craft" to be fascinating, and it's one that hasn't been mentioned, hmm, or how about "Telling Lies for Fun and Profit" that one was interesting... ...But I've never yet found a book as good as getting personalized advice. The author can only speak in generalities, and those generalities won't always apply, or you won't be able to see how they apply, or whatever.
