There has been some moderate buzz surrounding SourceTool.com this week - a vertical business directory which links buyers and suppliers. SourceTool indexes and organizes 500,000 business suppliers around the world according to UNSPC®, a product classification system developed by the United Nations Development Program. “What we like about UNSPSC® is that it is an actively managed classification system in the public domain that is used by the major supply chain software systems,” explained Dan Savage, CEO of TradeComet.com. While listings are free SourceTool asks that you include "sourcetool.txt" on your root directory as well as UNSPC numbers in your meta-tags.
