I have read all the books Richard mentioned and they are all excellent......this is one of my passions......another excellent read on the subject is Ultimate High, My Everest Odyssey, by Goran Kropp, a young swede who rode a bicycle from sweden to Everest in 96, then climbed to the summitt without supplemental oxygen. Unfortnately he died while climbing here in Washington state a couple years ago.
David Breashears, who Richard mentioned, wrote a good book called High Exposure, an Enduring Passion for Everest and Unforgiving Places. He made the IMAX film in 96 and ended up participating in the rescue during the tragedy told about in Krakaurs book Into Thin Air. Kropp also did his climb at that same time.
Good luck to all who will climb this year!!!!!......tom
