Here you will find the complete list of 12,000+ journals with Impact Factor. These journals are approved by JCR and are included in the JCR Journal list for 2021.
The Journal Citation Reports (JCR) is a database provided by Clarivate Analytics (formerly owned by Thomson Reuters) that provides information on the impact and influence of scholarly journals.
The JCR includes data on the number of citations received by articles published in each journal, as well as information on the journal’s circulation, acceptance rate, and other metrics.
The JCR is widely used in the academic community as a tool for evaluating the relative importance of different journals within a given field or discipline.
What is JCR Impact Factor?
The most well-known metric from JCR is the Impact Factor, which is calculated by dividing the number of citations received by articles published in a journal over a two-year period by the total number of articles published in that journal during the same period.
This gives a measure of how often the articles published in a journal are cited by other researchers.

It is important to note that JCR provides data on journals in the natural and social sciences, and in the arts and humanities. It does not cover journals in the field of medicine, which have their own citation report, the Journal Citation Reports in the Science Edition (JCR-SE) and the Journal Citation Reports in the Social Science Edition (JCR-SSE).
Should you care about the impact factor of a Journal?
Whether or not you should care about the impact factor of a journal depends on your specific needs and goals.
For some researchers, publishing in high-impact journals is important for advancing their careers and building their professional reputations. For others, the most important factor may be the audience or readership of a particular journal.
Additionally, Some fields have more stringent criteria for publishing papers, thus it may be important to publish in high-impact journals to be considered as a reputable researcher.
On the other hand, some fields may not be as concerned about the journal’s impact factor, the most important thing is the content and the advances in the field.
