This site http://search.ebay.co.uk/Orkney (for which I can't vouch, but have not heard ill reports) is currently carrying WPL Thomson's "New History of Orkney", now out of print, and copies of both Patrick Bailey's "Orkney" and Eric Linklater's "Orkney and Shetland": all good asets for those seeking to start an Orkney library.
My cousin just asked about Grahame hall: "I am curious as to the names of the owner and his family of Grahame hall where my grandparents worked before coming to Canada in 1912." Does anyone know anything about this location? Thanks, Darryl
