(SOLD)These special-edition, out-of-print hardbound books are rarely seen offered for sale. The publishers produced only 50 red-covered editions and 100 gray-covered editions, primarily for libraries. They have become highly prized collector's items (search previous sales here to see how often they are offered). Over 300 pages of insulator info!

All will be shipped at the affordable Media Mail rate through USPS within the US.

Red hardback: $95, plus actual shipping cost. (SOLD)

Gray hardback: $60, plus actual shipping cost. (SOLD)

Two-volume spiral softbound set: $45, plus actual shipping cost.
