Frequently asked questions

What is GKBook?

GKBook is a free general-knowledge site about the world: every country and its flag, A-to-Z reference lists such as colors, phobias and collective nouns, verified fun facts with their sources, and quotes worth keeping. Each article ends with a short quiz.

Is GKBook free?

Yes, all of it. Nothing sits behind a sign-up or a paywall; every page is open to every reader, in full.

How are the facts checked?

Every fact and every table row is checked against at least two independent sources, with official records and scientific papers preferred, and the sources are kept on file. Where sources disagree on a figure, the page gives both.
