Side note: Is it pronounced leading as in 'leed-ing' or 'led-ing'? I always thought it was the former, but since it's named after lead (the metal), I'm guessing it's the latter?

Is this the full book?

I always recommend two type books to people. First, Bringhurst. Second, once they've realized Bringhurst will be a lot of work, I recommend Thinking With Type. And then when they balk at paying for something that will make them better at their job I point them here. As long as they read something I guess.
