Uranium Resources, Production and Demand, also familiarly known as the "Red Book", is a biennial publication produced jointly by the NEA and the IAEA under the auspices of the joint NEA/IAEA Uranium Group. The first edition was published in 1965. Thirty editions have since been published. As the only government-sponsored publication tracking world trends and developments in uranium resources, production and demand, the Red Book is an authoritative source of information on the subject.
