Now you can access PACER documents (the ancient Federal court document system) without charge (as long as one other person has already purchased the same docs.) The PACER service provides on-line access to U.S. Appellate, District, and Bankruptcy court records and documents nationwide.
RECAP (PACER backwards) is an addon to the Firefox web browser that allows you to access PACER docs already purchased by another, and then shares any docs you purchase with others similarly.
You can read about it here.
Thanks to Dan (Engine Ecology) for this really cool and unusual bargain tip.
