Easy now, I just got it a few hours ago 
I haven’t read much of it yet, but the set consists of three heavy, hardbound volumes.
Vol. 1 is general information, lunar history, the Earth-Moon system, lunar observing equipment, photographing the Moon, observing tips and the first part of the main content “Crater-Hopping, Observing the Moon on day..” with day 1 to day 7..
Vol 2 is Crater Hopping from day 8 – 29 (last 14 days in one chapter), chapters about rays, flooded craters, riles, domes, wrinkles, TLP, measuring the Moon, drawing the Moon, occultations, eclipses, etc.
Vol 3 is a lot of appendixes: ephemerides, libration, catalogues of domes, halo craters, rays, rilles etc, Chinese, Hebrew, Hindu and Arabic lunar mansion systems, lists of old and new feature names, the updated atlas of Edmund Neison and a lot of other stuff.
Many, many pages with a lot of photos and drawings. I love moon-books and look forward to reading it all.
