The CAS Source Index, generally known as CASSI is a listing of the bibliographic details of journals and other periodicals indexed in Chemical Abstracts. It was originally published in paper form, but this was discontinued in 2010.[1] It is available as an electronic database with other Chemical Abstracts Service (CAS) products or as a free-standing CD-ROM: basic information is also available as a free web service.

A major use of CASSI is to determine the correct abbreviation for a journal title. Most chemical journals require journal titles to be abbreviated in line with Chemical Abstracts usage,[Note 1] which also ensures near-compatibility with ISO 4.[2][Note 2]

CASSI contains bibliographic details for about 80,000 periodicals indexed by Chemical Abstracts since 1907. The information includes full title, CODEN, ISSN, language of publication and publication history, as well as details of predecessor or successor publications.[3]

Notes and references

Notes

  1. ↑ Depending on the journal, there may be some leeway on abbreviations: Nature and Science are usually referred to by their simple names, although Chemical Abstracts has to disambiguate the abbreviations to Nature (London, U. K.) and Science (Washington, DC, U. S.) respectively.
  2. ↑ The main differences between CASSI and ISO 4 are: (1) CASSI capitalizes all words in an abbreviation, while the LTWA respects the capitalization rules of the source language; (2) CASSI does not use diacritics in abbreviations, and so has different rules for transliteration from Cyrillic script (eg Zh. instead of ž. for the abbreviation of the Russian журнал, žurnal).
