If they only sold for $400, they were not listed properly then.

Probably a stupid question: It looks like the code stayed roughly the same size up until WW2. Is the fact that is started to grow substantially afterward due to advances directly resulting from the war?

Advances in technology. Increased safety regulations (grounded receps, etc.). More required circuits (SABCs, bath, laundry.....). Today, it's AFIs, TR receps, etc.

It's a hardcover. I haven't seen a paperback.

Yes..... I have looseleafs from 1990 on.
