Sources for college football data

• James Howell's College Football Historical Results. The main source for historical College Football results used in these rankings for the premier division prior to 2000.
• Peter Wolfe College Football Results for the current season updated weekly. This is the main source for all results used in these rankings from 2000 to 2024.
• Kenneth Massey's Data. The best place on the Web for data on sports results. This is the main source for results used in these rankings starting 2025. It has also been an extremely valuable source since 1997 for information on other computer rankings as well at the various human polls.
• Wikipedia: WikiProject College Football contains a wealth of historical data for college football. I am slowly working on incorporating these data for the years prior to 2000 in the rankings.
• Nearly all NCAA and NAIA colleges now have webpages with historical data for most college sports. I am also working on incorporating these data, together with the data from the WikiProject and Howel, into the rankings.
