Have you found a typo, continuity problem or factual error in my book? Good! Here’s a wiki (a community-editable webpage) where we’re keeping track of errata. I’ll fix any errors I can in the electronic editions (though just in the canonical PDF, text and html versions, I have no way of editing the user-submitted versions). When the next edition of the treeware version of the book comes out, I’ll see to it that all the errata are collected there, too!
