Blue book, new and old

<p>I got a blue book back in 2005 or 2006 (I forgot when exactly). Will it be different from the one out there right now? Should I get a new one if I already have one from the past (due to updates, etc.)?</p>

<p>Nope, it's the same. . . . Sadly, Mr. Jackson met his untimely end before I became aware of this fact.</p>
