The Science Citation Index(SCI) is a citation index originally produced by the Institute for Scientific Information (ISI). Currently, the indexing is done by by Clarivate Analytics.
But, currently only the list of SCIE journals are provided by Clarivate Analytics via Web of Science (along with a few other indices). Hence, the question
How to get an updated list of SCI journals?
Also, I would like to know whether there is a quality assurance difference between SCI and SCIE presently. If there is no difference in terms of quality, then that means SCIE has practically replaced SCI and the above question (in bold) would be irrelevant.
