New York--The American Business Press is pondering further moves to extend its membership beyond its core of business-to-business publishers. The organization is mulling plans to invite company Web sites to become members, said Gordon Hughes II, ABP president. Earlier this year, the ABP's board approved a proposal to allow Internet publishers, such as VerticalNet, to join the organization as full voting members. That proposal will likely be approved by the full membership on Nov. 2, Mr. Hughes said. Additionally, the ABP plans to step up its efforts to recruit international publishers. The trade group suffered a pair of blows earlier this year when two members--CMP Media, which was purchased by Miller Freeman, and Ziff-Davis, which announced plans to resign its membership--dropped out of the ABP, taking with them a total of $300,000 in yearly dues.
