Walker-Hill deliberately eschews judgments about quality or value. It remains for users of this volume to separate the wheat from the chaff. She gives call numbers for works located at the Library of Congress and the American Music Center, and addresses of composers, publishers, and other sources. Women whose names changed are cross-referenced. Pseudonyms of those active in literature or popular music in addition to serious music are identified.
Single pieces are cross-referenced to collections from which they come.
More than twenty of the pieces cataloged are collected in a volume edited by the author and published in 1992 by the Hildegard Publishing Company. Besides the catalog itself, the book contains four helpful appendices listing published piano music, ensemble instrumentation, teaching pieces, and a chronology of surviving piano works before 1920. There are a few inconsistencies. An oxymoron, quartal triads, appears on p. 102. There are also rather more typographical errors than one might wish, but most are easily recognized and dismissed as such.
