Prompted in part by two major 2009 policy initiatives, this edition reflects new regulatory legislation. Following the objective, highly informative chapter on federal regulatory history and purpose, the editors detail 100 federal organizations in four main segments: major agencies, supplementary commissions, departmental agencies, and regulatory-oversight divisions. Logically organized by alphabetized umbrella agency, such as Justice, and then by division, like Antitrust, each multipage profile lists office location, personnel contacts, published titles, and defining legislation. An extensive appendix offers feedback methods and relevant acts and documents the language of ten related Executive Orders. VERDICT A meticulously compiled, one-stop subject reference.
