Everything on this site is derived from public records. Nothing is scraped from a commercial statistics provider, and nothing is asserted that a source does not support. Each page also lists the specific records behind it, so any individual claim can be traced rather than taken on trust.
Play-by-play event files from 1912 onward, game logs from 1871, and the ballpark register. This is where the games themselves come from — who pitched, who batted, what happened, where it was played and who umpired.
Terms: Used with the notice Retrosheet requires, reproduced below.
Season-by-season batting and pitching records, awards, All-Star selections, Hall of Fame ballots, and club season records. The career totals and the league-leader tables are computed from it.

The person spine: a stable identifier for each player, and the cross-references that let a Retrosheet id, a Lahman id and a Baseball-Reference id be recognized as the same person.

Photographs, Wikipedia links, heights, nicknames, positions, Hall of Fame membership, and the ballpark records used to identify each ground.
Terms: CC0 — dedicated to the public domain.
Every photograph on the site. Each file's license is checked before the image is used, and files whose terms do not permit publication here are refused rather than published under a guess.
Terms: Per file. Each image credits its photographer and license on the page it appears on, and links to the file.
The on-this-day feeds used to find events worth a page, and corroboration for events found in the game record.
