Query: Not worth the money

Don't even bother to purchase this book! I went through & counted how many of the EXACT patterns you can get for free online & it is 16!! I don't think it is ethical to put together a compilation of patterns that you can get for free (anyone with a computer can) and sell it as a "NEW" book. Just my opinion. Borrow it, but don't buy it!
