A few things to know about elections and voting resources. 

• The federal and individual state governments provide the official sources of government information, statistics, and data on elections and voting. 
• The U.S. federal government provides free public access to official elections and voting data through various agencies, including the U.S. Census, the Federal Elections Commission (FEC), and the U.S. Election Assistance Commission (EAC).

• Many well-known election and voter data sources, such as CQ Press, Dave Leip's Atlas of U.S. Presidential Elections, and L2 Voter collect, clean, and organize official U.S. elections and voting data for ease of access. Penn provides students and faculty access to these and other subscription-based resources, which are listed in this guide.
