Query: world record for poor proof reading

I have never read a book so littered with mistakes. To a neophyte this book must be so confusing as to be totally useless. Can you believe the author gives three different renderings of the acronym SGML within a few pages of each other. Many absolutely critical points are muffed by the most banal and obvious proof reading errors. The final straw is the tear out reference card which can't even get the rules for XML names correct. Really, it's just too, too bad.
