The file "jeffbagwell_war_historical.csv" contains wins above replacement (WAR) data -- according to JEFFBAGWELL (the Joint Estimate Featuring FanGraphs and B-R Aggregated to Generate WAR, Equally Leveling Lists), which averages together WAR from Baseball-Reference.com and FanGraphs -- plus various other metrics for MLB since 1901.
Note that this file includes players from the Negro Leagues recently added to Baseball-Reference's database. For those players (and any others without matching FanGraphs IDs/stat entries), Baseball-Reference data is used solely for WAR and the various run values, and "+" stats (indexed to league average) are not currently available.
One more note: Pitching JEFFBAGWELL now equally averages together WAR based on FIP (standard FanGraphs), runs allowed modified for defense (Baseball-Reference WAR) and WAR purely based on runs allowed (FG's RA9 WAR).
