Giving away the public domain docs the US gov charges money for

Professional provocateur Carl Malamud writes,

public.resource.org has created a mirror of NTIS.Gov's [National Technical Information Services] store that sells public domain materials. Our twist is that instead of sending you the materials, we'll release them back into the public domain for everybody to use. We mashed some of the materials up in a little infomercial here.
