With the new - free - google books app, you can download an enormous number of historical mountaineering books
written before 1930. The titles I have downloaded onto my iPad include books written by: Young, Jones, Workman, Abraham, Conway, Freshfield, Norman-Neruda, Collie, Mummery, Perry, Lunn, Haskett Smith, Dent, Raeburn, and Whymper.
