Standard journal impact factors
Researchers seeking to find appropriate publication venues and librarians seeking to develop strong and influential collections often rely on resources that provide measures of journal or individual article use in the research of others. Below is a short list of such measures.
Journal Citation Reports
The Clarivate Analytics Journal Citation Reports (JCR) is probably the most well known resource for journal impact factors. It is a fee-based subscription service to which St. Mary's does not subscribe. However, impact factor data is sometimes provided on publisher websites as a promotional tool for their journal. Contact us if you would like for us to check and see if we can find it for you.
As noted in the Eigenfactor.org website, this ranking and mapping system is an academic research project sponsored by the Bergstrom Lab in the Department of Biology at the University of Washington. The citation data used at Eigenfactor comes from Thomson Scientific's Journal Citation Reports (JCR). This database is freely available.
SCImago Journal & Country Rank
"The SCImago Journal & Country Rank (SJR) is a portal that includes the journals and country scientific indicators developed from the information contained in the Scopus® database (Elsevier B.V.)". The SJR rankings are freely available.
Google Scholar Metrics
Google Scholar Metrics provide an easy way for authors to quickly gauge the visibility and influence of recent articles in scholarly publications. This database is freely available.
CiteScore is a free service provided by Elsevier's Scopus indexing service. Unlike Journal Citation Reports, front matter material is also counted in the metric which may dilute the CiteScore metric of journals with extensive front matter material.
Citation counts have been the traditional means of assessing the impact of journals, individual articles, and the work of individual scholars. Changes in the technology of scholarly communication have provided additional measures to assess how information is acquired and used. There are several resources available that utilize these alternative metrics (altmetrics). Below is a short list of guides already created by other institutions which provide information about altmetrics.
Articles, Projects, and Blogs
Using various metrics to measure scholarship is not without controversy. Below are links to blogs, wikis, and articles that discuss assessment of scholarly research.
