The Science Citation Index (SCI) was officially launched in 1964,[1]and later was distributed viaCD/DVD.[2]Then in 1997, Science Citation Index Expanded (SCIE) superseded SCI, and becomes available online. SCIE is now owned byClarivate(previously the Intellectual Property and Science business ofThomson Reuters).[3][4][5][6][7]

The inde xing database covers more than 9,200 notable and significantjournals,across 178 disciplines, from 1900 to the present. These are alternatively described as the world's leading journals ofscienceandtechnology,because of a rigorous selection process.[8][9][10]

Accessibility

edit

The index is available online withinWeb of Science,[11][12]as part of its Core Collection (there are also CD and printed editions, covering a smaller number of journals).[13]The database allows researchers to search through over 53 million records from thousands of academic journals that were published by publishers from around the world.

Specialty citation indexes

edit

Clarivate previously marketed several subsets of this database, termed "Specialty Citation Indexes",[14]such as theNeuroscience Citation Index[15]and theChemistry Citation Index,[16]however these databases are no longer actively maintained.

The Chemistry Citation Index was first introduced by Eugene Garfield, a chemist by training. His original "search examples were based on [his] experience as a chemist".[17]In 1992, an electronic and print form of the index was derived from a core of 330 chemistry journals, within which all areas were covered. Additional information was provided from articles selected from 4,000 other journals. All chemistry subdisciplines were covered: organic, inorganic, analytical, physical chemistry, polymer, computational, organometallic, materials chemistry, and electrochemistry.[17] By 2002, the core journal coverage increased to 500 and related article coverage increased to 8,000 other journals.[18] One 1980 study reported the overall citation inde xing benefits for chemistry, examining the use of citations as a tool for the study of the sociology of chemistry and illustrating the use of citation data to "observe" chemistry subfields over time.[19]
