SJR- SCImago Journal and Country Rank

database

Provider: SCImago
Contents: , ,
Access Level: ,
Descriptions: Based on data indexed in SCOPUS, SJR graphs a number of metrics on scientific publications and publishing. Some unique aspects of the journal analysis include: proportion of cited to uncited/citable to uncitable articles; percentage of a journal's articles that are indicative of research resulting from international collaboration; ranking of countries and regions of the world according to publication output and citation; and an interactive map feature that generates graphic co-citation networks among disciplines, by country and time period. The opening page of SCImago sums it up: "Rank - Analyze - Compare - Visualize."

Journal Citation Reports (JCR)

database

Provider: Thomson Reuters
Contents: , ,
Access Level: , ,
Descriptions: The JCR gathers statistical data for the purpose of evaluating and comparing scholarly and technical journals, using citation data drawn from over 7,500 journals. Originally a part of the Science Citation Index, the Journal Citation Reports were also a great innovation that came to be considered the single impartial, authoritative measure of a journal's quality and influence. In recent years, there have been serious challenges to this view, and some alternative systems of journal evaluation have been introduced that have aimed to correct the problem of bias in the data on which this still very influential analysis system for journals was founded. Annual editions of JCR from 2000 to approximately the most recently-previous year are accessible online. Journal Citation Reports rates journals on the basis of: most frequently-citedby discipline; highest-impact in a field; and largest in a field.
