NASA technical books

I've got a few vintage NASA publications. Am wondering about a couple
of them in particular, whether they might still be of any scientific
value.
-- Measurement of Thermal Radiation Properties of Solids (from 1962
USAF / NBS / NASA symposium at Dayton OH)
-- Lunar Orbiter Photographic Atlas of the Moon (Bowker & Hughes,
1971)
They're fairly hefty & my shelf space is limited so am wondering
whether they're worth anything to anybody.
