About
Data Sources
Source categories, purposes, limitations, and correction paths for Hindsight Games games.
Yearbook
Yearbook uses Wikimedia On This Day material and event-specific articles as research inputs. These are reference sources, not an endorsement or partnership. Source pages can change or simplify history; a player can use the corrections process to question a clue.
Rough Draft
Rough Draft compares values from official or authoritative sources using the measurement defined for each paper. Source notes appear after completion, including material caveats about estimates, dates, models or scope. A stated comparison can still contain an error; use the corrections process to flag a value or definition.
Roster Relay
Roster Relay uses league-specific player and team-season records to apply its connection rule. Sports records can differ on transactions, roster status, franchise names, and season coverage. The shared team-season shown by the game is the rule for play, not a claim of league endorsement.
Names and rights
Data, team, player, and league names may be trademarks of their respective owners. References do not imply affiliation or endorsement.
