The following business-to-business exchanges are grouped either by product category and the predominant manufacturing supply-chain sector that buys and sells those products, or by business services available at the exchange and the predominant corporate function the services support (many of the exchanges listed may serve additional supply chains or support multiple corporate functions).
Within each product or service index, exchanges are listed in alpha order based on exchange name. Exchanges listed in this index were operating as of late December 2000. Given the volatility of the online exchange industry, some sites may have ceased or suspended operations or merged with other exchanges.
Listings of services and functions of the exchanges are based on information published at the exchange Web sites as of late December 2000 and are not based on actual business-to-business experiences with the exchange. Consequently, IndustryWeek's listing of an exchange should not be construed as an endorsement.
