Harrassowitz Music Services (http://www.harrassowitz.de/sp/music.html)

Several useful databases can be viewed from these pages:

• Scores database (primarily European Editions)
• Monuments of Music from Europe contains the most important Monuments of Music from Europe, including those of Eastern European countries and Israel. New volumes which are in preparation and the total number of volumes planned (as far as known from the publishers) are given for each work.
• Composers' Collected Editions from Europe includes the larger collected editions of composers which are currently in the process of being published. EXCLUDED are: most of the older Russian collected editions (e.g. Dunaevskii, Prokofiev, Chaikovskii), since many of the volumes from these works have not been available for quite some time; all of the Leipzig, Breitkopf & Härtel collected editions (e.g. Cornelius, Händel, Palestrina), reprinted on demand by Gregg in England, although these may be purchased from us; most collected editions which are currently published or reprinted in non-European countries (we have included a few titles from Israel and Japan).
