Rare: There is no copy of Clementi's edition of Op.110 in the British Library or the Beethoven-Haus and only one copy of either edition has been traced outside the UK (Op.111 is in Vienna). "Clementi's edition of Op.111 is quite independent of the editions published by Schlesinger....It is tempting to suggest that it is the most accurate edition of Op.111 ever to have appeared" (Tyson, 1963).   Beethoven sent the manuscripts of the Sonatas Op. 110 and Op.111 to Ferdinand Ries in London in the latter part of 1822.  The dedicatee of the C minor Sonata is still that indicated in Beethoven's letter of 18 February 1823 (ie Antoine de Brentano); whereas in Schlesinger's edition of April 1823 (not 1822, as stated by Kinsky), this was changed to the Archduke Rudolph.  The Field "Divertimento" in A major is also rare: The British Library contains only the piano part of this first edition.
