The Catholic Information Center was started by the Archdiocese of Washington years and years ago - well before OD came on the scene to run it. 

It was floundering and the cardinal at the time asked if OD wanted to run it.   Running a bookstore  (or running a parish for that matter) isn't something that OD jumps at because it takes energy away from its primary objective which is to give formation to members of OD.   When OD takes on something though they try to run things "very well".  And the CIC does run very well.

60K is I think less than 1 months worth of operating expenses.  

It's not a "joint venture".
