Rulemaking is the single most important function performed by government agencies. While Congress and the president provide the general framework for the government's mission, rulemaking fills in the details that define the law and delineate how each agency carries out its responsibilities. Cornelius Kerwin, and new co-author Scott Furlong, update this highly regarded text with new data, fresh analysis of interest groups' participation in rulemaking, as well as coverage of the Obama administration's early actions, from executive orders and key personnel to agencies' responses to changes. An invaluable and accessible guide to this intensely political process, Rulemaking contains the most current scholarship on a crucial yet understudied subject.
