If today's Electoral College news isn't enough, the free HarpWeek site <http://www.harpweek.com/> now offers a feature about another such controversy -- the one from the Hayes - Tilden election of 1876.
Description from the site:
HarpWeek has created this Website, primarily from the
pages of Harper and the general public with the historic
events of the Electoral College controversy of 1876-1877.
The organization of the site allows users to follow events
day by day, to acquire a more in-depth understanding by
reading the overview, and to gain insight into the press
period cartoons (most by Thomas Nast), along with
corresponding explanations of their historical meaning.
