The Science Citation Index Expanded (SCIE) is a citation index owned by Clarivate and previously by Thomson Reuters.[1][2][3][4] It was created by Eugene Garfield at the Institute for Scientific Information,[5] launched in 1964 as Science Citation Index (SCI). It was later distributed via CD/DVD[6] and became available online in 1997, when it acquired the current name.

The indexing database covers more than 9,200 notable and significant journals, across 178 disciplines, from 1900 to the present.[citation needed] These are alternatively described as the world's leading journals of science and technology, because of a rigorous selection process.[7][8][9]

Accessibility

[edit | edit source]

The index is available online within Web of Science,[10][11] as part of its Core Collection (there are also CD and printed editions, covering a smaller number of journals).[12] 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 | edit source]

Clarivate previously marketed several subsets of this database, termed "Specialty Citation Indexes",[13] such as the Neuroscience Citation Index[14] and the Chemistry Citation Index,[15] however these databases are no longer actively maintained.[as of?]

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".[16] 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.[16] By 2002, the core journal coverage increased to 500 and related article coverage increased to 8,000 other journals.[17] One 1980 study reported the overall citation indexing 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.[18]
