Buy space property book
Get your copy of the book here (Amazon), or here (Lulu, from which you can also buy Unreal Estate in e-book format for $5.99 which is a super idea, although I do like the hardcover on my shelf; you can also peek into a free preview).
By the way, this is the press release for the book (also appearing, I see, in slightly rewritten form in today's SpaceDaily) in which I got quoted saying something for which I may have to apologize to my law school property professor. I mean, I didn't actually fall asleep during that class; I may have drifted off now and again...
As Jeff notes, (also see my post here),Virgil's book is less a space law treatise and more of a historic overview of celestial property claims, dealings and profiteering. Pour yourself a chilled snake oil cocktail and dig in.
