Literature References in Industrial and Engineering Chemistry

for 1939

S TATISTICAL studies of the literature references in the Journal of the Americen Chemkl Society have

been made by Gross and Gross1 and by Sheppard,= in the Recueil des travaux chimiques des Pays-Bas by Pat ter~on,~ and in the Journal o f the Association of Ojicial as cultural Chemists by d r o f t . q u c h studies have been useful to librarians and others for indications as to which are the most consulted journals and for what length of time the articles in them continue to be in active use.

leading journal in the general field of chemical industry, It has seemed of interest to make a similar study of a ind for this purpose Volume 31 of Industrial and Engi-

T i e n c e , 66, 385 (1927). neering Chemistry (Industrial Edition) was chosen. 1 J. C ~ M . EDUC.. 12,472 (1935). Vet. frav. chim., 59, 538 (1940). This volume appeared during 1939, the last year in ' J. CHEW EDUC., 18. 315 (1941). which i t was practically unaffected by the war. The

514

numbers of citations to the different periodicals is given in Table 1. Journals cited under two or more names (as Z. angew. Chenz. and Angm. Chem.) are treated as one journal, but diierent names resulting from the division or union of journals have been re- garded as representing separate periodicals. In some cases all the papers and bulletins issued by the same Government agency (as the U. S. Bureau of Mines) have been treated as one periodical.

There were in all 3159 citations from 512 periodicals in 16 languages. In addition there were 419 citations to books and pamphlets, 36 to theses, 27 to unpublished papers and addresses, 65 to personal communications; and 461 to patents, as follows: U. S. patents, 345; British, 64; German, 25; French, 22; all others, 5.

In previous studies it has been found that the journal being examined cites itself oftener than i t does any other journal. This is particularly true of Ind. Chem. Eng., possibly because it covers a wide field while the majority of the serials which it cites are special in nature. This may also account for the very large num- ber of different serials cited.

A striking fact brought out by Table 1 is the appear- ance in it, among the industrial publications, of many well-known journals devoted to pure science. This

seems to be an excellent illustration of the dependence of applied chemistry on nonindustrial research.

A classification of the journals according to their fields shows: pure science, 142 (1032 citations or one- third of the whole); nonchemical engineering, 68 (271 citations); general chemical industry, 46 (966 cita- tions); rubber, 15 (130 citations); fuels, 19 (97 cita- tions) ; - water, sewage, and sanitation, 19 (92 citations) ; petroleum, 16 (85 citations); soils, fertilizers, etc., 30 (67 citations); and smaller numbers for various other chemical industries.

References to abstract journals are relatively few (e. g., Chem. Abstracts, 8; Chem. Zentr., 5; Brit. Chem. Abstracts, 1). Apparently most authors assume that readers can look up the abstracts without this help.

Table 2 shows the representation of different coun- tries by the numbers of their periodicals cited and num- bers of citations.

Table 3 shows the relation between the age of articles and patents to the frequency of their citation. Accord- ing to it, nearly half the citations were to articles and patents five years old or less, and two-thuds to those less than ten years old, but certain ones continue to be cited for a long time. The oldest article referred to was published in 1810.
