In 1980, John Pugsley published the book The Alpha Strategy. It was on The New York Times Best Seller list for nine weeks in 1981.

Many books were published in the wake of the Great Recession from 2008 and later offering survival advice for various potential disasters, ranging from an energy shortage and crash to nuclear or biological terrorism.
