       The difference between Sci and scie: SCI is a scientific citation index, while scie is an extension of SCI. Scie not only covers all the contents of SCI (3100 journals), but also adds other journals that SCI has not searched.

　　SCI refers to academic journal papers published in SCI journals included in the scientific Citation Index (SCI). SCI is a citation journal edited and published by the American Institute of scientific information (ISI), which was founded in 1964. It can be divided into printed version, CD-ROM version and online version.

　　Scie is the expanded edition of scientific Citation Index (i.e. online edition). Scie is the CD-ROM edition of some publications that later entered the catalogue, which can also be called the expanded edition. Strictly speaking, the CD-ROM edition or the expanded edition cannot be regarded as SCI publications, but some scie publications have high impact factors, which are actually irrelevant to the impact factors. Scie mainly depends on the ratio of published articles to citations.
