Query: can you say typo?

this one is a poorly written book with lots of typos. Things that could have been easily caught by a spell/grammer checker. I "cannot not" believe that some one proof read this book and did not find something wrong with "that0" book. :-)The material is also confusing at times. I don't mean to be picky but I saw some recursive definitions. For one thing, headers could have been numbered and that would have solved a lot of confusion. And, oh a lot of grammatical mistakes.On the positive front, it does have web site references at the end of each section. That seems to be very useful.I would not recommend this edition of the book. Maybe, the next revision would be better.
