Loompanics Unlimited was an American book seller and publisher specializing in nonfiction on generally unconventional or controversial topics. The topics in their title list included drugs, weapons, survivalism, anarchism, sex, conspiracy theories, and so on. Many of their titles describe some kind of illicit or extralegal actions, such as Counterfeit I.D. Made Easy and Opium for the Masses, while others are purely informative, such as Uninhabited Ocean Islands, How to Buy Land Cheap and The Muckraker's Manual (recommended by Stewart Brand).
