ERRATA
14 Dec. 1996 Sonata 88, formerly listed as in D# Major, changed to D flat Major
5 May 1997 Comprehensive Concordance: Rubio 42=Marvin 38 deleted; M.38 not in Rubio edition.
5 May 1997 Rubio - Marvin Concordance: see last entry 5 May. Also, M. 42 changed to Rubio 98 (previously listed as Rubio 42).
28 May 1997 - Added Marvin cross-reference for Rubio 45. Note that this is not the Sonata 45 heard in the Van Asperen set of sonatas, which is actually the "Sonata por la Princesa de Asturias." Apparently Rubio 45 is a member of this suite.

7 Nov. 2005 - Concordance corrected to reflect errors in Ife / Truby numberings.
