The Impact Factor® (also known as the Journal Impact Factor) is a proprietary product in Journal Citation Reports, owned by Clarivate Analytics (formerly Thomson Reuters).
JCU does not subscribe to Journal Citation Reports. It is possible to check the JCR (Journal Citation Reports) Quartile Category for individual journals by searching for records in Web of Science and then clicking on the name of the journal in lists of records or the "View Journal Information" in records for articles.
The Impact Factor is not field-normalised, meaning that it does not take account of variations citation behaviours in different disciplines e.g. there is a tendency for life sciences journals to have higher Impact Factors than social sciences journals. The Impact Factor should therefore only be used when making comparisons within the same discipline.
