I, too, have the current "Whiskey Bible". And, while I don't always agree with Murray's overall ratings/conclusions, I find the tasting notes themselves invaluable in directing evaluation of newly-tried whiskeys. It's a reference -- and just like you wouldn't base a paper or study on a single reference source, I don't use Murray exclusively for whiskey/bourbon info. But as a single reference, he is useful. I rely on Chuck's book, too, for common-sense, insider bourbon facts and opinions. The Regans' "Bourbon Companion", too. Then I make up my own mind, if I hadn't already to begin with.
