Scholarly Communication Services at WSU: Tools: Journal Citation Reports and Alternatives

This guide is designed to increase awareness of significant issues associated with scholarly communication. It also presents resources for WSU researchers who wish to explore alternative avenues for sharing their scholarly work with a global audience.

Journal Citation Reports and Alternatives: Introduction

This page provides information about journal impact metrics using data from Web of Science, Scopus, Google Scholar, and alternatives. Prior to publishing, you may wish to select a journal based on its journal impact factor, or its prestige and influence within particular disciplines.

Web of Science Journal Impact Metrics: Journal Citation Reports/InCites

Scopus Journal Impact Metrics

Although the WSU Libraries does not have a subscription to Scopus, Scopus data is used in a number of freely-available journal evaluation resources. Note- see the first link to get journal metrics without a Scopus subscription.

Google Scholar Journal Metrics

Google Scholar Metrics provide an easy way for authors to quickly gauge the visibility and influence of recent articles in scholarly publications. Scholar Metrics summarize recent citations to many publications, to help authors as they consider where to publish their new research.

Alternative Tools for Assessing Journal Impact

Impact Definitions from Thomson Reuters

Journal Impact Factor: As calculated by Thomson Reuters: The journal Impact Factor is the average number of times articles from the journal published in the past two years have been cited in the JCR year.

Eigenfactor: The Eigenfactor score calculation is based on the number of times articles from the journal published in the past five years have been cited in the JCR year, but it also considers which journals have contributed these citations so that highly cited journals will influence the network more than lesser cited journals. 

Article Influence: The Article Influence determines the average influence of a journal's articles over the first five years after publication.  It is calculated by Thomson Reuters by dividing a journal’s Eigenfactor score by the number of articles in the journal, normalized as a fraction of all articles in all publications. 

Impact Definitions from Elsevier

Source Normalized Impact per Paper (SNIP): Created by Professor Henk Moed at CTWS, University of Leiden, Source Normalized Impact per Paper (SNIP) measures contextual citation impact by weighting citations based on the total number of citations in a subject field.

SCImago Journal & Country Rank (SJR): Developed by Professors Félix de Moya, Research Professor at Consejo Superior de Investigaciones Científicas and Vicente Guerrero Bote at University of Extremadura, SCImago Journal Rank (SJR) is a prestige metric based on the idea that 'all citations are not created equal'. With SJR, the subject field, quality and reputation of the journal have a direct effect on the value of a citation.

Impact Per Publication (IPP): The IPP measures the ratio of citations in a year (Y) to scholarly papers published in the three previous years (Y-1, Y-2, Y-3) divided by the number of scholarly papers published in those same years (Y-1, Y-2, Y-3).

See this article for more information about SNIP, SJR, and IPP.
