Query: Optical Character Recognition edition---full of typos and mistakes

As you will find on the second page of the book, this edition is produced by using OCR technology on an old print. In fact, starting on the very first page you will immediately start to notice mistakes like random punctuation marks and wrong letters. The blurb claims that OCR allows cheaper books to be available, but Amazon's price on this edition is quite expensive for a 100-page paperback.
