Performers and schools will find this volume useful to identify music written for the sometimes odd instrumental combinations that require music to perform. In addition, Gifford provides access to many difficult-to-find arrangements of famous works for oboe, oboe d'amore, and English horn. Indexes of publishers, instruments, and composers make it possible to attempt to purchase or locate the listed items. Library of Congress call numbers are provided for each entry. Also listed are method books and books about these instruments at the Library of Congress. Gifford's book is unique in its coverage of a large, specialized collection and is recommended for purchase by high school, conservatory, and college libraries supporting active performing programs.
