The John Murray Archive's transfer to the National Library of Scotland has been of huge advantage to Byron studies, giving more or less unlimited leisure to trawl through catalogues and folders. Much new material is becoming available all the time, including these three letters to Byron, which have hitherto lain unnoticed. They do not appear in The Letters of John Murray to Lord Byron, ed. Andrew Nicholson (Liverpool University Press, 2007), in The Letters of Thomas Moore, ed. Wilfred Dowden, 2 vols (Oxford: Clarendon Press, 1964), or in Byron's "Corbeau Blanc": The Life and Letters of Lady Melbourne, ed. Jonathan David Gross (Rice University Press 1997).
