1998: full score in Leonard Bernstein: Orchestral Anthology, vol. 2 in the Boosey & Hawkes Masterworks Library series; 43 pages of music (numbered pp. 1-43). It has been newly generated by computer notation software. On the bottom right of p. 1 is the note "Corrected Edition 1998." There is no plate number for this item, although the other three works in the anthology are reprints with their original plate numbers.
NOTE: the lists below cannot presume to be comprehensive; rather these are the variants I caught in fairly quick perusals while preparing the post. Moreover, this is only a collation of the printed sources: I have not examined the autograph(s). Because of the substantially different orchestra, the 1994 score of the full show is mentioned only when relevant to some specific detail. The corrections first introduced in the 1990 printing (that is, where 1990 agrees with 1998 but not 1960) are highlighted below by an asterisk.
