Journal Citation Reports® offers a systematic, objective means to critically evaluate the world's leading journals, with quantifiable, statistical information based on citation data. By compiling articles' cited references, JCR helps to measure research influence and impact at the journal and category levels, and shows the relationship between citing and cited journals (from the publisher's website).
The Library's Web of Science Core Collection includes:
Essential Science Indicators can determine the influential individuals, institutions, papers, publications, and countries in their field of study — as well as emerging research areas that could impact their work. This unique and comprehensive compilation of science performance statistics and science trends data is based on journal article publication counts and citation data from Web of Science™.
Conduct on-going, quantitative analyses of research performance and trends in science. Rank top scientists, institutions, countries, and journals in 22 specific fields of research based on journal article publication counts and citation data.
Highly cited papers can be selected by field, or from the results of a search by scientist, institution, country/territory, journal, or title word. Highly cited papers returned by the search are ranked by total number of citations. Other rankings are by publication year and journal title.
Every two months,Essential Science Indicators from Thomson Reuters lists a new crop of what it calls hot papers in science. Hot papers are selected by virtue of being cited among the top one-tenth of one percent (0.1%) in a current bimonthly period. Papers are selected in each of 22 fields of science and must be published within the last two years (from the publisher's website).
