The Theme collections, ranging from 45 to 305 pages in length, include articles written over a 25 year or longer period. They show development of ideas as well as addition of new topics.

The choice of articles to include was perhaps somewhat suggestive. Some articles may seem "off-topic" but are included because they do have a bearing on the central theme.

In the "Tourism" theme issue, we include not only articles about tourism itself, but about what tourists from Earth might find interesting about how the settlers live, not just tours of craters etc.

The Lunar Economy issue is absolutely critical. Pioneers must export enough to pay for needed imports. This issue lists major as well as minor ways in which a lunar economy can not only be solvent, but even prosperous. Indeed, without a strong lunar economy, any opening on Mars is likely to fail.

The volume "surface activities" includes such diverse topics as road construction, railroads, waysides, small rural outposts, surface arts and crafts, and "Out-vac" sporting and recreational activities.

"Eden on Luna" may seem an odd title, but this volume includes a wide variety of articles showing how settlers will learn to make themselves at home on the Moon, and, considering that they must live "downwind and downstream of themselves" how they must give priority attention to air and water refreshening, "religious" recycling of anything made with elements scarce on the Moon (e.g. carbon, nitrogen, hydrogen and more.), and how such a lifestyle demands that education reflect it, how living areas must be dominated by plant life, and on and on. This volume also includes many articles on how lessons learned on the Moon will help those remaining on Earth to repair and refresh their ailing home planet.

Indigenous Lunar "Arts and Crafts" will play a major role in getting pioneers to the point that they truly feel at home on the Moon.

We have collected articles on "Asteroids" and "Mars" because they will be essential trade partners if Lunar settlement is to succeed.

We have gathered scattered articles about other worlds in our "Solar System," and beyond - "starbound" - because our venture on the Moon. if successful, maybe  just the beginning of "the rest of the human Out of Africa epic" from the "Intercontinental" expansion to the "Interplanetary" expansion and just possibly to an "Interstellar" Expansion.

There may well be further additions to this Themes Collection. No hints at this time.

Hopefully this effort to arrange the wide variety of articles in the past (now 26) years of MMM will help the editor reorganize this material into "MMM the Book" with the working title of "A Pioneers Guide to the Moon."   

Enjoy.                 PK
