Corrections to citations

In my last posting I had mistakenly cited Michael Alvarez's book, Information and Elections, when I should have cited his 2002 article, "Ballot Design Options."

Also, I cited Scott Roberston, but he was actually citing Bederson, et al. 2003, "Usability of large scale public systems: Electronic voting system usability issues."

Both of these mistakes are corrected in the post below.
