A person I know has employed her own method of preserving these venerable old "scrolls." She visits the Kingdom Hall during meetings to do a bit of research in the Kingdom Hall library. She finishes her research and exits the KH discreetly before the meeting concludes. When she gets home she discovers that some publications sought refuge in her capacious handbag. She has "received freely" an extensive collection of "free Bible literature." I completely approve of her stealthy methodology; it is utterly harmonious with the life-saving Noah-like educational work of the WTB&TS.
Persons who find that their trust in Watchtower dogma has left them economically disadvantaged may find this method helpful in supplementing their income - the "life-saving truths" can be further distributed to other seekers of truth via eBay or other internet vendor stalls. Jehovah jireh and all that, y'know.
Plunder them, sack them. Take the silverware from Jah's feast-table.
