This page preserves unpublished sources on the history of proportional representation in American local government. Some came from the late Leon Weaver, via Doug Amy of Mount Holyoke College. Other items came from Dennis Pilon of York University. The rest I have found myself. Contact me if you know of others!

Note: there is a running bibliography of recent, published, empirical work on preferential voting at my blog. These works cover both single-winner ranked-choice voting and proportional representation via the single transferable vote.
