Only the surnames of many of the composers are given in the registers and catalogues of DGA and Electrola GmbH
which sometimes means that the composers are difficult to identify. This index only lists composers for whom I have be able to obtain (apparently) independent evidence that they
are the composer of the stated work and whose full name is known.
The main sources that I have used are "The New Grove Dictionary of Music and Musicians", "Greene's Biographical Encyclopedia of Composers" by David Mason Greene,
"The Concise Baker's Biographical Dictionary of Composers & Musicians" compiled by Nicolas Slonimsky,
"Deutscher Biographischer Index" published by K G Saur München (2004), and the internet.Would anyone able to identify any of the unidentified composers please inform me (with sources)
