Deep ocean zone. Usually associated with hydro-thermal vents or volcanic activity. As for a marketable source of the mineral, perhaps someday. However, as manganese is still readily available above water, under water mining costs make the nodules much to expensive to gather commercially.

I would look on E-Bay under "vintage magazines" or something like that and see if anyone else has same type up for auction.  See what their opening price is and if anyone has bid on it.  That would help.  It would also tell you if there is an interest in the particular magazines you have.  I've been selling some antique crystal on there and sometimes there is just no market for some of it, though, it could change in a week.

Do a search. These values have to be out there somewhere if you can ask for them as you have.
