Stepping Through The Stargate by P.N. Elrod (2004, Paperback)

I decided to buy it because of my love for the movie and tv series. It's a compilation of essays written by writers, actors, scientists, etc. A couple of the essays were dumb, but for the most part it was interesting. One scientist discusses the science of having a stargate, and how it might be possible to create one (if our technology was 1,000 years more advanced). Overall it was a pretty good book. Definately worth a read, though unless you live and die for Stargate-- maybe see if your library carries it.
