If you like fiction, "Antarctic Navigation" by Elizabeth Arthur got me started on reading everything I could find on Antarctic exploration.
I 2nd all the books above. The Fiennes book "Race to the Pole: Tragedy, Heroism, and Scott's Antarctic Quest" is wonderful. But I think the one Roger mentions is "Mind over Matter" which is the story of his crossing of the Antarctic.
Also the journals of Robert Falcon Scott are quite interesting and touching.
At the other end of the earth, you might like "In the Land of White Death" by Valerian Albanov.
Last December I saw an amazing photo exhibit, "The Heart of the Great Alone," at the Queens's Gallery in London of photos taken on the Shackleton and Scott expeditions. Unbelievably beautiful large prints, and very moving - it included shots taken at the pole on a camera found in the tent with the bodies of Scott, Bowers, and Wilson. After having read all these books, I almost felt like I'd known these men, and to see the exhaustion and disappointment on their faces really hit me.
