In their heyday, Thomas Register of American Manufacturers was a 34-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.

Thomasnet has expanded to provide not only product and company information, but also online catalogs, computer-aided design (CAD) drawings, news, press releases and blogs.

Since November 2010, Thomasnet has been a founding partner of GlobalTrade.net, a marketplace for international trade service providers.

Starting in 2010, Thomasnet began reaching out to its database of manufacturers to get a better understanding of where the community was, where their shortcomings were, and where they saw the landscape going in the future.
