Billy has taken part in the writing of several books relating to the development of young baseball players. In 2005, he and Cal wrote "Play Baseball the Ripken Way: The Complete Illustrated Guide to the Fundamentals", and co-authored by Larry Burke. Working with Rick Wolff, the brothers released the book "Parenting Young Athletes the Ripken Way" in 2006 in response to Cal seeing too many young athletes who he felt were being pressured unnecessarily by their parents. He said, "I was thinking, `This just creates too much pressure on kids.' They need to find an environment in which they can explore their game ... without all these kinds of pressures being brought to bear. Once I started thinking about it, I saw we had more than enough to fill a book." They also wrote "Coaching Youth Baseball the Ripken Way", co-written with Scott Lowe and published in 2007.
