The Washington Information Directory (WID) is a topically organized reference resource that lists contact information for federal agencies and nongovernmental organizations in the Washington metro area along with a brief paragraph describing what each organization does related to that topic. In addition, WID pulls together 55 organization charts for federal agencies, congressional resources related to each chapter topic, hotline and contact information for various specific areas of interest (from Food Safety Resources to internships in Washington), and an extensive list of active congressional caucuses and contact details. WID has two appendices, one with thorough information on congresspersons and committees, and the second with governors and embassies.
