Baseball is the only professional sport where every single thing that every player on the field does is recorded — good or bad. Mark McGwire even once commented that during his seventy home run season the media was counting the number of cups of coffee he actually drank each and every day.
Baseball Almanac is pleased to present an unprecedented collection of official baseball record books that will bring to life those "cups of coffee" and keep you up to date as the baseball records fall.
"He just blew it (Nolan Ryan strikeout number five-thousand) by me. But it's an honor. I'll have another paragraph in all the baseball books. I'm already in the books three or four times." - Rickey Henderson

Only five players in baseball history have ever had 40 home runs and 40 stolen bases during the same season — do you know who they are?
Can you name the active players who are slugging average leaders? How about the on base percentage leaders? Search the baseball record books and see which active players (names appear in bold print) are Major League record holders.
