Query: Could have been a great book

I am only on chapter 3 and have actually enjoyed the subject up to this point but I don't believe I have ever read a techbook with so many gross mistakes. For example, page 76 states "ANSI does use a BOM" when in fact it should have said "ANSI does not use a BOM" which is easily concluded from prior text. Also, the very first code example in ADO is horribly written. One gets the impression after awhile that this is the rough first draft of the actual intended book. Wrox doesn't even list this book as one of their products on their website and I have yet to find the public errata website for this book.My criticism notwithstanding, the book could have been a great book had someone taken the time to clean it up. I get the impression someone pushed these poor guys into getting this thing "on the street" way before its time.
