In 1982, Carl Childress offered a 42-page, photocopied scholarly manuscript called The Rules of Baseball: A Comparison. That modest beginning led to an invaluable book, now called Baseball Rule Differences, known everywhere in the baseball world as "The BRD." Officiating.com is proud to offer the 26th edition of this unique book, where you'll find information on the National Federation, NCAA, NAIA, and Official Baseball Rules that you can't get anywhere else.

The 2008 BRD comes in a convenient 5.5" x 8.5" size with a spiral binding - perfect for studying!
