Additional Sources of Journal Metrics
In this section, we discuss two additional resources that you can use to locate bibliometric information for journals in a variety of academic disciplines. These two resources are Scimago Journal & Country Rank and Google Scholar Metrics.
Scimago Journal & Country Rank
Site address: https://www.scimagojr.com/
Scimago Journal & Country Rank (SJR) is an online portal that provides bibliometric information for journals published in a wide variety of disciplines. This website provides various metrics, but is best known for a metric known as the SCImago Journal Rank indicator (also abbreviated as SJR).
The method for calculating the SJR is similar to the one used for Clarivate's Journal Impact Factor (JIF). However, in assessing a specific journal, SJR takes into account the prestige of the publications where citations to that journal appear. For example, if an article from Journal X is cited in a highly prestigious journal, this citation will carry more weight than a second citation that appears in a less recognized journal. The citation received in the highly prestigious journal will contribute more to the SJR score.
The SJR website is great for evaluating individual journals as well as for making comparisons between different publications. You can look up metrics for specific journals by using the search box or clicking on a journal's title wherever it appears on the site. You can also search by subject area and find out which journals have the highest SJR scores within that field. The website also allows you to perform searches by country of publication.

Google Scholar Metrics
Site address: https://scholar.google.com/citations?view_op=metrics_intro&hl=en
Google Scholar has a section called "Metrics". By visiting this section, you can identify top journals in specific academic fields and obtain bibliometric information for individual journals. The metrics provided in Google Scholar Metrics are h5-index and h5-median. These are based on the more widely used h-index, a metric which is explained in the "Other Metrics" section of this guide.
The definitions for h5-index and h5-median, as provided in Google Scholar Metrics, are as follows:
- "h5-index is the h-index for articles published in the last 5 complete years. It is the largest number h such that h articles published in 2015-2019 have at least h citations each."
- "h5-median for a publication is the median number of citations for the articles that make up its h5-index."
