If you are lucky enough to live within easy travelling distance of London, you might be interested in some new stuff they've got on display in the Treasures room ...
(Well, I say 'new,' obviously not new new)
Photograph of Scott's Polar party (Scott, Oates, Wilson and Evans) - presumably one of the photos taken by Birdie, if he's not in it
South Polar Times
Illustrated leaflet advertising films and slides of the exhibition - I assume this is relating to Ponting's touring show
Captain Scott's penultimate diary showing 'The Pole' written in large letters
Captain Scott's final diary including the account of Oates's death
Reference numbers and other (non-Polar) things on display are listed
here.
