I'm shocked by the apparent lack of copy editing or even proof reading on the electronic version of this edition. The scholarly apparatus is excellent, but hard to access readily while reading because there is no functioning table of contents. The text itself frequently includes not only misspelled words but random punctuation marks, such as parentheses substituted for "J"s. No wonder it's less than 3 bucks. Why can't they just use the typesetting from the print version?
That said, the scholarly material in this edition is outstanding.
