This dictionary was originally derived from the Concise Science Dictionary, first published by Oxford University Press in 1984 (fifth edition, retitled Dictionary of Science, 2005). It consisted of all the entries relating to chemistry in this dictionary, including physical chemistry, as well as many of the terms used in biochemistry. Subsequent editions included special feature articles on important topics as well as several chronologies tracing the history of some topics and short biographical entries on the chemists and other scientists who have been responsible for the development of the subject
