I had not seen this site before. The archive goes back to the very beginning of college basketball, around the early 1900's, if I'm not mistaken.
They also cover baseball, football, hockey, and soccer.
College basketball archive: rosters, schedules, stats, players, coaches, conference standings, conference tournaments, NCAA tournaments, polls, awards, etc.
They have every UD roster, schedule, player, coach, stat, etc.
