I found an interesting Presidential website titled US Presidents: Lists and Records. The site describes itself as, "The presidents of the United States are so much fun. Understanding them helps us understand American history. We have compiled a series of lists about the presidents, and will be adding more as we think of new categories."
Included are very useful items such as the 1995
historical ranking of 41 presidents conducted from Siena College, which Presidents were left-handed, the relative
share of popular and Electoral College vote each president won, and regular and
pocket vetoes issued by each, etc,
