The Association of Directory Publishers (ADP) is an international trade association serving the directory publishing industry since 1898. ADP membership includes online and print publishers, app developers and designers, advertising agencies and suppliers to the online, mobile and print publishing industry. The directory publishing industry is the original “local search engine,” widely known as the medium that brings buyers to sellers at the exact moment they are ready to buy. As this ever-evolving world of “search” expands, whether it is print, online, social networks or mobile devices, ADP will continue to be at the forefront to assist its members in connecting buyers to sellers.
