Fauré continued to work intermittently on the Requiem, and by 1893 he judged the score ready to be published (although the proposed publication fell through). Several attempts have been made to reconstruct the score as it was in 1893. The Fauré specialist Jean-Michel Nectoux began working on it in the 1970s, but the first edition to be published was by the English conductor John Rutter in 1989. Nectoux's edition, jointly edited with Roger Delage, was published in 1994. They had the advantage of access to important source material unavailable to Rutter: a set of orchestral parts discovered in 1968 in the Madeleine and a score made in the 1890s by a bass in the Madeleine choir and annotated by Fauré. "Music and Letters" judged the Rutter edition, "makeshift and lacking in the standards of scholarship one expects from a university press". "The Musical Times" considered the Nectoux and Delage edition "invaluable".
