There was a wee coding flummox in the book source that resulted in the table of contents not being interpreted correctly by the popular Stanza iPhone ebook reader. Those have now been fixed.
You can find these downloads and more on the Stanza Library Page ((Which now also has a shorter and friendlier URL. You know. Except that you still have to type out ‘spontaneous derivation’ on your itty bitty keyboards. They don’t autocomplete well, either. Sorry about that.))
