As a result of meticulous historical research using official batting, pitching and fielding statistics, boxscores, and the literature of the period, we have produced highly accurate seasons for the years 1920-1960, 1962-1963. (See Deluxe Past Seasons for more years)
For Classic Past Seasons, we don't have access to the pitch-by-pitch and play-by-play data that is available for current seasons. So we use other analytical techniques (using year-by-year and career data) and a review of boxscores and news accounts from the period. Left/right strategy remains a big part of the game, however. It's just that the left/right advantage is the same for every player, instead of being based on real-life differentials.
Some Classic Past Seasons (1920-1926, 1934, 1948, 1954-55) also include a complete set of real-life player transactions and game-by-game starting lineups that you can use to recreate past seasons with even higher levels of accuracy.
