Retrosheet, established in 1989, focuses on computerizing play-by-play data of pre-1984 major league baseball games. Over the years, Retrosheet has expanded its scope while maintaining a core emphasis on major league games. Noteworthy milestones include the addition of game logs, box scores, and player statistics in 2001, and the inclusion of Negro Leagues data in 2020.

The organization, led by President Tom Thress since 2022, continually works to preserve and provide valuable historical baseball information. Retrosheet is indebted to its dedicated volunteers whose contributions have been instrumental in its success. The website features a memorial page honoring key contributors and retains historical content for reference.

Retrosheet welcomes volunteers and donations to support its mission of enriching the understanding of baseball history through comprehensive data collection and analysis. For more information, visit Retrosheet's website or contact Tom Thress for inquiries or contributions
