Book excerpt: The National Golf Foundation, the recognized leader in golf research since 1936, has just published the GOLF COURSE DIRECTORY. Taken from NGF's continually updated database of over 16,000 facilities, THE GOLF COURSE DIRECTORY is a two-volume, 563-page resource tool that provides facility name, address, phone number & key contact personnel. There is also information relative to facility type (e.g. daily fee, municipal or private), size (regulation, par 3 or executive), total number of holes, year opened, & whether the complex includes a practice range. THE GOLF COURSE DIRECTORY is also available in lists & mail labels. The price of the print directory is $199. ISBN 1-57701-079-5. As part of the introduction of this new directory, NGF has also created three additional niche directories from their extensive database: THE DRIVING RANGE DIRECTORY, of 1,700 facilities, Price: $99.00, ISBN 1-57701-080-9; THE PAR-3/EXECUTIVE GOLF COURSE DIRECTORY, listing 1,700 facilities, Price: $99.00, ISBN 1-57701-082-5; THE OFF-COURSE GOLF RETAIL SHOP DIRECTORY, listing 2,000 stores, Price: $99.00, ISBN 1-57701-081-7. The entire family of print directories, mail label services & lists are under the umbrella of NGF's new MarketLinks products.
