Journal Citation Reports (JCR) is a unique multidisciplinary journal evaluation tool that provides a journal evaluation resource based on statistical information from citation data. By statistically compiling references, JCR measures the influence of research at the journal level and reveals the interrelationships between citing and cited journals. The quantifiable statistical data offered by JCR provides a systematic and objective method to determine the relative importance of a large number of journals within specific subject categories.
The new version of JCR not only includes the world's most influential journals covered by the Science Citation Index Expanded (SCIE) and the Social Sciences Citation Index (SSCI) but also adds journals from the Arts & Humanities Citation Index (AHCI) and the Emerging Sources Citation Index (ESCI). The new JCR covers over 20,000 journals from more than 110 countries or regions, spanning over 250 Web of Science subject categories.
Information provided by JCR includes:
- The number of articles published in journals, ranked in descending order to compare publication volume.
- The number of times each journal was cited in a given year.
- The ratio of articles published in a journal in a given year that were cited within the same year.
- The average citation rate of journal articles, calculating the impact factor for each journal in a specific year.
- Calculation of the half-life of cited and citing literature for each journal.
Functions of JCR:
- Identify the journals with the greatest academic influence in a specific discipline.
- Find the most frequently cited journals.
- Discover the hottest journals.
- Analyze and understand journal literature "self-citation" situations.
- Identify review journals.
- Compare journal manuscript selection habits.
