The International Union of Pure and Applied Chemistry (IUPAC) is an association of National Adhering Organizations, which represent the chemists of different member countries. IUPAC was founded in 1919 and its primary purpose is to provide nomenclature and standards for the international field of chemistry. A consistent set of internationally accepted atomic weights was deemed a necessity by the scientific community because of the relevance of these values to science and technology, as well as to trade and commerce. The standard atomic weights of the elements are regularly evaluated, recommended, and published in updated tables by the Commission on Atomic Weights and Isotopic Abundances (CAWIA) of IUPAC. This is a collection of published reports, draft manuscripts, correspondence, and reprints generated by the CAWIA of IUPAC. A portion of the collection has been digitized and is available online.
