In 'Paving the Way for Apollo 11' David Harland explains the lure of the Moon to classical philosophers, astronomers, and geologists, and how NASA set out to investigate the Moon in preparation for a manned lunar landing mission. It focuses particularly on the Lunar Orbiter and Surveyor missions.
Informative but took a while to wade through. There's a lot of places where the text is broken for 3-6 pages by images and tables, making it hard to read. There's also one chapter in the middle which has around 50pages of lunar photographs that felt a little redundant to me (they weren't high enough resolution for scientific interpretation, but there were too many to look through for general interest). But if you're looking to read up on this era of the Apollo programme and NASA, this one will tell you pretty much everything from NASA side, as well as a smattering of the Soviet side as well.
