not seeing the connection

I just typed "legal self-help churches" into the search box at barnesandnoble.com and was given four results:

51% Minority: How Women Are Still Not Equal and What You Can Do about It

German-English Genealogical Dictionary

Trial by Trial: Destiny of a Believer

and

Gratitude Works: Open Your Heart to Love

I'm not sure what any of that has to do with legal self-help for churches, but the German one looks pretty interesting . . .
