Since the appearance of the third edition of 'Ethnomusicology', still more titles have come to my knowledge, all issued before September 1958. The reader will find them in this Supplement. I have used this opportunity to add some more synopses of training possibilities for ethnomusicologists, together with an additional selective list of recordings issued, as far as I know, in 1958. Finally I may express my gratitude to Messrs. Nijhoff who gave me the opportunity to improve my endeavor to give a practically exhaustive survey of what has been published in the field of ethnomusicology up to August 31, 1958.
