Anyone know who's now publishing Official Baseball Rules?

[UMP25]

For years The Sporting News has published Official Baseball Rules, and we were fortunate to obtain the rule books at an association rate of 50% off the retail price, which was a big help when many are ordered at once. However, my contact at The Sporting News recently told me they are no longer publishing the book. When I asked him who was, he told me he had no idea and that no one there knew anything.

I've searched around but so far have had no luck. Does anyone know who is the official publisher now? With all the changes in OBR this year, it'd be nice for those of our guys who want this in the typical handy book format to be able to get it.
