Schubert: Thematic Catalogue of all his Works in Chronological Order, also known as the Deutsch catalogue, is a numbered list of all compositions by Franz Schubert compiled by Otto Erich Deutsch. Since its first publication in 1951, Deutsch (abbreviated as D or D.) numbers are used for the unique identification of Schubert's compositions.
The Deutsch catalogue was first published in London in 1951, as Schubert: Thematic Catalogue of all his Works in Chronological Order, compiled by O. E. Deutsch, in collaboration with Donald R. Wakeling.
1978 ion: NSE VIII/4
In 1978, as part VIII Supplement / Volume 4 of the New Schubert Edition (NSE), an updated version of the catalogue was published in German.
A few compositions that had been undated in the first ion received a new number (usually followed by a letter), e.g. D 993 was renumbered to D 2E.
The original 1951 ion (in English) was re-issued several times, for instance in the United States by W. W. Norton. The 1978 version, published by Bärenreiter, had a double objective: it was not only a list of Schubert's works as such, it was also the compendium of all scores published by that publisher in the New Schubert Edition.
New versions in English
In 1995 Dover Publications republished the 1951 ion, with updates derived from scholarship that had been published since 1951.
New versions in German
From 1983 compact versions of the catalogue appeared, ed by Werner Aderhold and others.
Changes to the numbering of Schubert's works were minor in these later ions.
