Query: Good book, bad editing

David Hume's "The natural history of religion" is a very valuable text. However, this edition is an unreadable product because the editors did not proof read the book after scanning and OCR of the text. The result is a book with many words missing letters and words strung together without spaces. A typical example of a hasty product. Amazon should impose a quality control on both editing and the correct page numbering. As such, this edition is useless. There are two other editions available on Amazon, I suggest one tries his or her luck with those. For me, this was wasted money.
