IUPAC Nomenclature of Organic Chemistry

"Chemical nomenclature is used to identify a chemical species by means of written or spoken words and enables a common language for communication amongst chemists. Nomenclature for chemical compounds additionally contains an explicit or implied relationship to the structure of the compound, in order that the reader or listener can deduce the structure from the name. This purpose requires a system of principles and rules, the application of which gives rise to a systematic nomenclature.

IUPAC Nomenclature of Inorganic Chemistry

"The Rules of Inorganic Nomenclature (the 'Red Book'), first published in 1958 by the International Union of Pure and Applied Chemistry (IUPAC), were most recently updated as Nomenclature of Inorganic Chemistry 1990. This new 2005 edition of the 'Red Book' clarifies and updates recommendations concerning the names and formulae of inorganic compounds and reflects major recent developments in inorganic chemistry. Moreover, it presents recommendations fully consistent with the principles of the nomenclature of organic chemistry.

IUPAC Compendium of Chemical Terminology

"The Compendium is popularly referred to as the 'Gold Book', in recognition of the contribution of the late Victor Gold, who initiated work on the first edition. It is one of the series of IUPAC 'Colour Books' on chemical nomenclature, terminology, symbols and units (see the list of source documents), and collects together terminology definitions from IUPAC recommendations already published in Pure and Applied Chemistry and in the other Colour Books.

Roget's Thesaurus

"Roget's Thesaurus is composed of six primary classes. (...) Each class is composed of multiple divisions and then sections. This may be conceptualized as a tree containing over a thousand branches for individual 'meaning clusters' or semantically linked words. Although these words are not strictly synonyms, they can be viewed as colours or connotations of a meaning or as a spectrum of a concept. One of the most general words is chosen to typify the spectrum as its headword, which labels the whole group.

Electropedia: The World's Online Electrotechnical Vocabulary

"Electropedia (also known as the 'IEV Online') is the world's most comprehensive online electrical and electronic terminology database containing more than 20 000 terms and definitions in English and French organized by subject area, with equivalent terms in various other languages (...). (...) Electropedia is produced by the IEC, the world’s leading organization that prepares and publishes International Standards for all electrical, electronic and related technologies – collectively known as 'electrotechnology'.

Thesaurus für Parlamentsmaterialien

"Die Parlamentsdokumentation unterstützt Sie (.) mit dem Thesaurus 'PARTHES'. Er enthält einen festgelegten Wortschatz an Schlagworten, die den Dokumenten zugeordnet werden. Aber auch Synonyme werden im Thesaurus vollständig erfasst und verweisen auf das festgelegte Schlagwort; so wird das Schlagwort 'Extremismus' benutzt für das Synonym 'Radikalismus'. Sie können in einem solchen Fall mit beiden Bezeichnungen suchen, da die Verweisung sicherstellt, dass Sie auch mit 'Radikalismus' alle mit 'Extremismus' erschlossenen Dokumente finden.

Environmental/Chemical thesaurus

"The Environmental/Chemical Thesaurus approaches scientific language control problems from a multidisciplinary view. The Environmental/Biomedical Terminology Index (EBTI) was used as a base for the present thesaurus. The Environmental/Chemical Thesaurus, funded by the Environmental Protection Agency, used as its source of new terms those major terms found in 13 Environmental Protection Agency data bases. The scope of this thesaurus includes not only environmental and biomedical sciences, but also the physical sciences with emphasis placed on chemistry.
