The New Campaign Finance Sourcebook has been integrated with the award-winning and frequently visited Brookings website to provide a timely, interactive tool for policymakers, journalists, and scholars. Four of the country’s leading experts on campaign finance reform have contributed original essays on important facets of finance law and administration. The essays are accompanied by a list of corresponding documents available on the website. The book offers a thorough overview and analysis of this highly controversial issue, including the history of campaign finance regulation and the current state of the law, current practices and trends in the flow of money, the constitutional debate, the use of political party money, issue advocacy, public financing of presidential elections, implementing and enforcing campaign finance laws, and campaigning on the internet. The authors conclude with a broad overview of alternative approaches to reform. The related website (www.brookings.edu/campaignfinance) features sidebars that correspond to the book’s chapters as well as associated documents. The site is frequently updated with recent developments in campaign finance regulation and analyses of current court cases and administrative decisions. There are also links to advisory opinions from the Federal Elections Commission, nonprofit organizations that study reform, and related publications-.
