In the following inventory, I have divided the manuscripts into three sections:
1. 138 autograph manuscripts by Koechlin (1905-1945) plus one letter to Charles
Shatto of 15 March 1946 (MS 139). Of these, only MSS 14 & 134-8 are not Koechlin's own
2. Music by Koechlin copied by Catherine Urner. These
compositions (dating form 1895 to 1935) are numbered from I to XII.
Manuscripts by other composers (1929-35), notably Catherine Urner, Ernest Le Grand and
Jeanne Herscher-Clément. These are numbered from i to xiv.
