The Thomas Register of American Manufacturers, was once known as the "big green books" and "Thomas Registry", and was a multi-volume directory of industrial product information covering distributors, manufacturers and service companies within thousands of industrial categories.
The books were first published in 1898 by Harvey Mark Thomas as Hardware and Kindred Trades. In their heyday, Thomas Register of American Manufacturers was a 36-volume, 3 section buying guide offering sourcing information on industrial products and services, along with comprehensive specifications and detailed product information from thousands of manufacturers. The company stopped publishing its print products in 2006.
