I decided early on to see how much I could learn about Antarctica using Internet tools. This lists gives hyperlinks to some of the more interesting things I found, and searches very much like those I used.
I've also listed some of the very few books that seem to be available about Antarctica. Grandma and I were both very surprised by the scarcity of books written about Antarctica. We were also surprised to find that most of the books that do exist are about the explorers, and not about the place itself.
