Filling an important gap in scholarship, Professor Cowden's new bibliography provides complete and authoritative information on major conductors of permanent orchestral ensembles since the time of von Weber and Berlioz. Cowden has selected 1, 249 conductors on the basis of citations in standard music references, biographical studies, autobiographies, and contributions to the pedagogy of conducting. Publications in English and several European languages are cited. The first section, "Collective Works, " gives detailed information on titles devoted to concert and opera conductors and related titles containing additional material on conductors and conducting. The section on individual conductors is arranged alphabetically by artist. Further sources and references are offered in appendixes and an index of authors is included.
