PW's offices are now at 360 Park Ave. South, New York, N.Y. 10010., at the corner of Park Ave. and 26th St. Our main phone number is (646) 746-6400. While the area code and three-digit prefix have changed, the four-digit extensions for PW staffers remain the same. Our e-mail addresses have also changed, with @cahners.com being replaced by @reedbusiness.com, although e-mail sent to the old domain will continue to be delivered.
