Journal Citation Reports®

Journal Citation Reports is a comprehensive and unique resource that allows you to evaluate and compare journals using citation data drawn from over 10,000 of the most highly cited scholarly, peer reviewed technical journals from more than 2,500 publishers in over 80 countries. It is the only source of citation data on journals and includes virtually all areas of science, technology, and social sciences.

As a research tool, Journal Citation Reports can show you the:

  • Most frequently cited journals in a field
  • Highest impact journals in a field
  • Hottest journals in a field
  • Leading journals in a field
  • Related journals in a field

Citation and article counts are important indicators of how frequently current researchers are using individual journals. By tabulating and aggregating citation and article counts, Journal Citation Reports offers a unique perspective for journal evaluation and comparison. It is recognized as the leading authority for evaluating journals.


Essential Science IndicatorsSM

Essential Science Indicators provides Internet access to a unique and comprehensive compilation of essential science performance statistics and science trend data derived from Thomson Reuters data. The chief indicators of productivity (overall influence) are journal article publication counts. Total citation counts and cites per paper are indicators of influence and impact (weighted influence).

It is important to recognize that the data in Essential Science Indicators are limited to Thomson Reuters-indexed journal articles only. No books, book chapters, or articles published in journals not indexed by Thomson Reuters are taken into account either in terms of publication or citation counts.

Essential Science Indicators is divided into four main sections:

Citation Rankings: Using total citation counts and cites per paper, rankings are determined for the most cited authors, institutions, countries, and journals.

Most Cited Papers: This analysis provides a collection of the most highly cited and hot papers. Papers are selected based on percentile rankings in specific fields of science and time periods.

Citation Analysis: This analysis includes Baselines and Research Fronts to identify criteria for highly cited papers and to track trends in current research.

Commentary: These brief editorial discussions provide guidance on data analysis and interpretation. The information enhances the tables, charts, and other data sets presented in the previous sections.
