Colonies in Space by T. A. Heppenheimer, 1977, Warner Books, ISBN: 0-446-81-581- 0
Toward Distant Suns by T. A. Heppenheimer, 1979, Stackpole Books, ISBN: 0-449-90035- 5 Copies of both of these bookscan now be read online as part of the Space Settlement section of the website of the National Space Society. The total Space Settlement section now exceeds 10,000 pages and obviously has a great deal of additional material on Space Settlements that may be of interest.
