This unique reference book is a compendium of makers and manufacturers of every variety of musical instrument made in the United States today. It provides names and addresses of instrument makers indexed alphabetically. Each entry gives all known information on the total and annual number of instruments the maker has produced, the number of workers in the shop, the year the individual or firm began manufacturing instruments, whether the instruments are available on demand or made to order, and whether a brochure is available from the maker. Complete cross-references are provided for companies known by more than one name, for partnerships, and for parent and subsidiary firms. Instruments are also indexed, and makers are listed by state for the convenience of the reader. Lists of schools of instrument making and relevant organizations and publications are included as appendixes. The directory will serve two major purposes. First, it will be an invaluable source of information for historians and for the rapidly growing number of collectors of musical instruments, who will be able to use the data gathered here in appraising instruments and tracing their history. The second purpose is simply to increase communication among instrument makers and to make their names available to retail and wholesale outlets for their products.
