This list is based on details gleaned from online catalogues (mainly Amazon’s Good Reads website, which seems even more comprehensive than Google Books) and from the catalogues of the six Legal Deposit Libraries of Ireland and the UK (the Bodleian in Oxford, the British Library in London, the Cambridge University Library, Trinity College Library in Dublin and the National Libraries of Scotland and Wales). I have also examined the six-volume Collected Works at the British Library and the Cambridge University Library.
