JERSEY CITY, N.J., June 30, 2005 - Thomson TradeWeb, part of The Thomson Corporation (NYSE: TOC; TSX: TOC), a leading global provider of integrated information solutions to professional customers, announced today that BNP Paribas (BNP) has joined TradeWeb's growing online corporate bond marketplace as a liquidity provider.
