Thomas Register®

The Thomas Register of American Manufacturers, known as the "big green books" and "Thomas Registry", was in its heyday, a 34-volume, 3 section buying guide offering instant sourcing information on industrial products and services, along with comprehensive specifications and detailed product information from thousands of manufacturers. First published in 1898 as a single volume by Harvey Mark Thomas as Hardware and Kindred Trades, it grew to be known as "the purchasing bible" and "the bible of industry" by industrial professionals across North America and around the world. Its 100th and final edition was published in 2006.

Today, Thomas Register is the proprietary database powering the foundation of ThomasNet.com.

In 2000, CADRegister.com was launched offering users over 20 million CAD drawings.

In 2005, the leading provider of Internet sourcing and marketing solutions for industrial buyers and sellers, announced that it will discontinue its print publications, reflecting an over ten-year transition to the Internet as the primary information source of the industrial market. Following the 2006 edition of the Thomas Register of American Manufacturers, Thomas Industrial Network ceased publication of this print directory, familiarly known to industry as the "Big Green Books." The Thomas Register Regional Buying Guides were also discontinued as well. The full information from these publications, and much more, will continue to be available free-of-charge at ThomasNet.com using Thomas Register database to power the foundation of ThomasNet.com.
