If you go to the main Space Settlement page:
http://www.nas.nasa.gov/About/Education/Sp...ment/index.htmlScroll down to the section on books and other resources.
There you will find the online version of the 1977 study that NASA
actually published and excited my teenage imagination with promises
of giant orbiting colonies by the 1990s (that's what the newspapers
said). Of course they also promised me manned Mars landings
and lunar colonies by the 1980s.
The other book to check out is the CoEvolution Book on Space
Settlements, also from 1977.

Hopefully the idea has just been delayed, not abandonded.
