Another work that some may be interested in checking out is the McClintock-Strong set at $50.

I realize that the set is dated...but for the money/value and wealth of information it is well worth the money.
Looks good. I have a bid in.
I'm in on this already. I have it in another format and the sheer volume and breadth of valuable information outweighs the age factor IMHO as well.
