^^ I think EWOLD is worth reading -- or at least having as a reference -- because it contains the stuff discussed on these forums; indeed, it helped form the stuff. If anything, because it is old (and LaBerge was not omniscient) it is actually missing things, like DEILD and the possible value of supplements, but that might not be important.

What it does is consolidate all the basic stuff into a simple, readable format, and omits much of the crap and repetition that forums tend to generate. Plus it defines WILD and DILD (for the first time, BTW) as they were meant to be described, so you can understand what exactly they are (i.e., they are not techniques), without all the (mostly useless) glitter that's been added on over the years. It's also indexed, so you can look things up specifically when you need an answer or reminder.

So, if you are an accomplished LD'er, reading EWOLD will likely teach you nothing new about the art. But if you're looking for a reference book that nicely explains the very foundations of what LD'ers do, this is the book.
