Query: This particular version of this book is NOT RELIABLE

This version of this classic book is a ripoff.Somebody OCR'd it and printed up a bunch of copies and is selling it on Amazon. You can find the exact same .PDF for free on the web with the same typos.There are so many typos that you really can't discern the meaning of many portions of this book- vital portions.I gave up trying to read it after page 5 when I realized it was just confusing me. Truly incoherent.Don't waste your money. Amazon, stop selling this fake book. There is not even any copyright and publisher information in the beginning of the book.
