British Chemical Abstracts

Chemical Abstracts Service. The Chemical Abstracts Service (CAS), a division of the American Chemical Society, has produced Chemical Abstracts (CA) since 1907. Since the demise of Chemisches Zentralblatt and British Chemical Abstracts CA has been the preeminent medium for documenting new pubhcations in the field of chemistry and chemical engineering. CA documents chemical pubHcations of all types. It is not a patent database per se, but its patent component is larger than most databases devoted entirely to patents. Thus, for example, the number of patent references in CA for the years 1991—1993 ranged from 95,500—99,400 per year. 

No references to the original literature are given in the text. This is because the introduction of such references would have considerably increased the size and therefore the price of the book. However, a discussion on the literature of analytical chemistry is given in the Appendix. With the aid of the various volumes mentioned therein — which should be available in all libraries of analytical chemistry — and the Collective Indexes of Chemical Abstracts or of British Chemical Abstracts, little difficulty will, in general, be experienced in finding the original sources of most of the determinations described in the book. 

British Chemical Abstracts. These were commenced in the year 1871 and were included in the Journal of the Chemical Society. In 1926 the abstracting was taken over by the Bureau of Chemical Abstracts abstracts were then published in two parts Part A Pure Chemistry (formerly issued by the Chemical Society) and Part B Applied Chemistry ... 

The abbreviations of the titles of journals are those employed in British Chemical Abstracts. The abbreviated title is followed by the year, volume number (in heavy type), and page. 

Beilstein is the most comprehensive list of organic compounds. The main series, volumes 1-27, 30 and 31, part I, covers the literature up to 1910. The first supplement, volumes 1-27, and the subject and formulae indexes constituting volumes 28 and 29, survey the literature up to 1919. The second supplement, volumes 1-27, and the subject and formulae indexes constituting volumes 28 and 29, covers the period 1920-1929. For compounds not listed in Beilstein , i.e., for those which first appear in the literature after 1929, the indexes of the Abstract Journals Chemical Abstracts, ChemischesZentralblatt or British Chemical Abstracts (to 1953) should be consulted. The Collective Formula Index to Chemical Abstracts, 1920-1946, is extremely useful. For general reference work Heilbron will be found less cumbersome than Beilstein , although of necessity not so comprehensive. 

British Chemical Abstracts (Sections A and B) issued by the Bureau of Chemical Abstracts, and Chemical Abstracts of the American Chemical Society, should also be consulted for recent references.

The importance of abstracting Japanese scientific articles, otherwise wholly or partially inaccessible because of the linguistic barrier, was recognized early by the German Chemisches Zentralblatt, the American Chemical Abstracts the Journal of the Chemical Society London) (abstracts 1871-1925), and the British Chemical Abstracts. Since its first appearance in 1907, Chemical Abstracts has given increasing attention to Japanese chemical literature. This is described by the editor, E. J. Crane, in two articles 8, 9) from which the following statistics are taken. 

Faraday s Encyclopaedia of Hydrocarbon Compounds (Fig. 30) edited by J. E. Faraday and A. S. Freeborn (Butterworths) is a loose-leaf compilation in 18 volumes of data on hydrocarbons arranged by the Richter system to Cj4Hi8 and taken from Beilstein and the three abstract journals, British Chemical Abstracts, Chemical Abstracts and Chemisches Zentralblatt. References to the original literature are given to show for each compound its molecular and structural formula, its names, occurrence in nature, methods of preparation, detection and...
