Interest groups and other "group concepts" of politics dominated explanations of American government and policy-making in the 1950s and early 1960s and, as filtered through the concept of pluralism, have provided what is arguably the most lasting and perhaps the most persuasive theorizing on political decision-making in the United States. Representing Interest Groups and Interest Group Representation explores both the strengths and weaknesses of the current research on interest groups. It points to what needs to be done, the major intellectual concerns that should guide the research, and some of the more productive ways to approach the significant research questions.
