Licenses & credits
Most works in our library are United States federal government publications, which are in the public domain (17 U.S.C. §105) — and every one of them is available free of charge from its publisher at the source links below. What you pay us for is verification, clean offline packaging, plain-text editions, and continuous updates — never the underlying works themselves.
Offline Survival Hub is not affiliated with, or endorsed by, any publisher listed here. Reference to any agency, product, or organization does not constitute its endorsement or recommendation by the U.S. Government or any agency. We do not alter the substantive content of government works; our editions note their edition dates, and superseded documents are labeled historical. Copyright is claimed only in our original additions, curation, and software (17 U.S.C. §403).
