Interspersed with hundreds of terms and their definitions, the comprehensive Green Guide includes more than 3,000 dealers, appraisers, auctioneers and other service providers in New England. Each individual dealer entry begins with the business’ name, address, phone number and Web site (if applicable), followed by detailed information including the price range of inventory; size of retail space; associations to which the dealer belongs; directions to the shop and the owner’s name. Finally, the editors use a format they call "QuickCodes" to let readers know what kinds of items they’ll find in each shop. Informative and essential to all collectors in and around New England, the Green Guide makes any summertime treasure hunt complete.
