The rules for naming organic and inorganic compounds are contained in two publications, known as the ''Blue Book''{{ref|BlueBook}} and the ''Red Book''{{ref|RedBook}} respectively. A third publication, known as the ''Green Book'',{{ref|GreenBook}} describes the recommendations for the use of [[symbol]]s for [[Physical quantity|physical quantities]] (in association with the [[IUPAP]]), while a fourth, the ''[[Gold Book]]'',{{ref|GoldBook}} contains the definitions of a large number of
technical terms used in chemistry. Similar compendia exist for biochemistry{{ref|Biochem}} (in association with the [[IUBMB]]), analytical chemistry{{ref|Anal}} and macromolecular chemistry{{ref|Macro}}. These books are supplemented by shorter
recommendations for specific circumstances which are published from time to time in the [[Scientific journal|journal]] ''[[Pure and Applied Chemistry]]''.
