Professor David Lublin of American University has created electionpassport.com, which has election returns for the lower house of the national legislature of 80 nations. The list of 80 countries does not include some countries, such as the United States, the United Kingdom, Canada, Australia, and others in which the election returns are already easily accessible.

Some of the entries include elections as old as 50 years ago. The web page is a good resource for knowing the names of political parties that participate in elections in the listed nations.
