CODEN – according to
CODEN became particularly common in the scientific community as a citation system for periodicals cited in technical and chemistry-related publications and as a search tool in many bibliographic catalogues.
History
The CODEN, designed by Charles Bishop (of the Chronic Disease Research Institute at the University at Buffalo, State University of New York, retired), was initially thought as a memory aid for the publications in his reference collection. Bishop took initial letters of words from periodical titles, thereby using a code, which helped him arranging the collected publications. In 1953[1] he published his documentation system, originally designed as a four-letter CODEN system; volume and page numbers have been added, in order to cite and locate exactly an article in a magazine.[2] Later, a variation was published in 1957.[3]
After Bishop had assigned about 4,000 CODEN, the four-letter CODEN system was further developed since 1961 by
Although it was soon recognized in 1966 that a five-character CODEN would not be sufficient to provide all future periodical titles with CODEN, it was still defined as a five-character code as given in ASTM standard E250 until 1972.[7] In 1976 the ASTM standard E250-76 defined a six-character CODEN.[8]
Beginning in the year 1975, the CODEN system was within the responsibility of the American Chemical Society.[9]
Today, the first four characters of the six-character CODEN for a periodical are taken from the initial letters of the words from its title, followed by a fifth letter—one of the first six letters (A–F) of the alphabet. The sixth and last character of the CODEN is an alphanumeric check character calculated from the preceding letters. CODEN always uses capital letters.
In contrast to a periodical CODEN, the first two characters of a CODEN assigned to a non-serial publication (e.g. conference proceedings) are
In 1975, the International CODEN Service located at Chemical Abstracts Service (CAS) became responsible for further development of the CODEN. The CODEN is automatically assigned to all publications referred on CAS. On request of publishers the International CODEN Service also assigns CODEN for non-chemistry-related publications. For this reason CODEN may also be found in other
Current sources
CODEN assigned until 1966 can be looked up at the two-volume CODEN for Periodical Titles issued by L. E. Kuentzel. CODEN assigned until 1974 were published by J. G. Blumenthal.
Finding a current CODEN is now best done with the online database of
CASSI online is the replacement for CASSI as a printed serial issue (
