I participate in a long-standing AL-only auction league that for years has had a positional eligibility requirement of playing a position only once in the past two years.

Our league has used The Baseball Register (publ. by Sporting News) as the official source for positional eligibility, including for minor-leaguers.  But it seems that the book is no longer being published this year.  We draft a week into the season, so time is not yet critical, but we're searching for a new print source with all the minor league positions.  The league commissioner isn't willing to use the Internet during the auction and wants a paper source on hand for draft-day use.

What alternative to The Baseball Register would you recommend?
