Query: The best books available on SQL SERVER

The Guru Guide books are the best books available for SQL SERVER. I have all three and never ceased to be impressed with how much I learn each time I read one of them.Each book requires and rewards careful rereading. There is always more there than you glean the first time. I am still reading the first one nearly four years after I originally bought it. I never cease to find some new nuggest when I research a solution to my latest SQL SERVER challenge.I also like the non-technical writing in each book. The personal anecdotes, the essays, the quotes at the head of each chapter: they all give you the impression that you are being taught by, as Ron Soukup says, a veteran developer who knows what he is talking about because he has lived it.
