We've made lots of additions to the player data on College Basketball Reference in recent years. In an effort to make it a little more clear what data we have and what data we don't have, we've made this coverage map back to 1947-48.
Our rosters are essentially complete back to 1992-93, and our coverage of box score stats is also nearly complete back to that year (aside from minutes played, turnovers, personal fouls and offensive/defensive rebounds).
For seasons before 1992-93, it's important to note that our rosters are not 100% complete. It was NCAA practice for many years to combine the stats for non-rotation players on team stat sheets under the label "Others." So for many teams we have stats for the eight, nine, ten, etc. players who received significant playing time, but not for the players with negligible playing time. Additionally, we're missing 621 school seasons completely (mostly in the 40s and 50s). So when we say we have points for 98.8% of players in 1947-48, that means we have points for 98.8% of the players in our database for that season (which excludes players lumped in as "Others" or players on teams we are completely missing).
If you happen to have any of the data we're missing, please let us know. Over time, we hope to fill in as many gaps as possible.
