Journal Citation Reports can show you the most frequently cited journals in a field, highest impact journals in a field largest journals in a field. Citation and article counts are important indicators of how frequently current researchers are using individual journals.
Citation data is drawn from approximately 12,000 scholarly & technical journals & conference proceedings from 3,300+ publishers in over 60 countries. Data from Science Citation Index & Social Science Citation Index in Web of Science is included. Journal Citation Reports vs. Web of Science: A key difference between the Web of Science & JCR is that the Web of Science is continually updated, while the JCR data represent a snapshot from a specific time, namely, the date when the data were extracted for analysis. Web of Science is an evolving record of the dynamic world of scholarly communication with new source content continually added, including citations. JCR, on the other hand, is an annual report on the citation impact of a defined set of journals at a given moment in time.
Therefore, attempts to use Web of Science data to replicate JCR metrics will lead to results that will vary from those reported in JCR.
