Before there was Baseball-Reference.com, there was "The Bill James Handbook," the annual statistical compilation of the baseball season. The "Handbook" still exists, and it's still wonderful -- 600 pages of stats and essays and delightful nuggets of information.
As always, the bulk of the book is the player register -- career numbers for every player who played in the majors in 2018 -- but there are sections on managers, team defense, ballpark ratings, the Hall of Fame, leaderboards, pitchers' repertoires, shifts and much more.
