Most of Arthur C. Clarke's nonfiction books are collections of scientific articles he has written. This collection of some of the first emails ever made is a great read. It gives a great insite into the production of the film version of 2010. Some of the best parts are from writter-director-cinematographer Peter Hyams as he struggles to find dophines, sattilite dishes, actors, heat sheilds, money, spacecraft designs, and other such things. If you like Arthur C. Clarke's books or like Peter Hyams' films, you should definetly get this book.
