Journalytics Medicine

Journalytics Medicine

• With in-depth information on over 7,000 verified medical journals and 16,000 predatory journals, this curated database provides submission guidelines, detailed metrics, historical trends, and more. It helps researchers, librarians, funders, and administrators discover, verify, and evaluate quality medical journals.
• Users can assess verified medical publications across 37 disciplines by browsing, searching, or filtering for specific goals. Every publication included in Journalytics Medicine has been hand-verified and evaluated using a comprehensive set of selection criteria. Journal listings include bibliographic information, submission and manuscript details, access model, fee, and reuse information, and citation-backed metrics providing measures of discipline strength, influence, and attention.
• Each entry in Predatory Reports displays information on how to identify the journal in the real world as well as a comprehensive report detailing each violation that was uncovered during the journal’s evaluation. Journals are examined by Cabells review teams against more than 70 behaviors that contradict standard industry practices and are indicative of deception. Predatory Reports provides complete records of a publication’s behaviors broken down by level of severity in categories such as integrity, peer review, publication and business practices, fees, indexing, and more.

Journal Citation Reports via Web of Science

You can access Journal Citation Reports (JCR), a product of Thomson Reuters,via Web of Science (look for the link at the top of the page). Published annually, JCR provides a number of journal impact measurements for journals in the sciences and social sciences. Reported metrics include Impact Factor, 5-year Impact Factor, Immediacy Index, and others. Since 2007, JCR has also included Eigenfactor Metrics.

Google Scholar Metrics

Google Scholar Metrics includes a top 100 list of journals for particular subject fields ranked using their 5-year h-index. You can look at top journals in particular subject categories and sub-categories. The underlying data come from Google Scholar. Sections on Metrics, Coverage, and Inclusion tell you more about how the rankings were derived.

Highlights of Journal Metrics

Journal Impact Factor

• Frequency with which the 'average article' in a journal has been cited in a particular year or other defined time period using data from Journal Citation Reports (look for the link at the top of the page)..
• The 'classic' Impact Factor uses a 2-year citation window, but a 5-year Impact Factor is also available.
• Cannot be used to compare journals across disciplines.
• Available via Thomson Reuters InCites Journal Citation Reports (look for the link at the top of the page).

Eigenfactor and Article Influence Scores

• Eigenfactor: Measurement of the 'importance' or 'influence' of a journal.Citations from high-quality journals are weighted more than citations from lesser known journals.
• Article Influence: Calculated by dividing the Eigenfactor by the number of articles published in the journal.
• Both scores use a 5-year citation window, use data from Journal Citation Reports, and are meant to adjust for citation differences across disciplines, since different disciplines have different standards for citation and different time scales on which citations occur.
• FAQs about Eigenfactor and Article Influence Scores.
• Available on Eigenfactor website, or via Journal Citation Reports.

SJR (SCImago Journal Rank)

• Uses data from Scopus, with a 3-year citation window.
• Weighted by the prestige of a journal. Subject field, quality, and reputation of the journal have a direct effect on the value of a citation. SJR also normalizes for differences in citation behavior between subject fields.
• Available on SCImago Journal and Country Rank website.

SNIP (Source Normalized Impact per Paper)

• Uses data from Scopus, with a 3-year citation window.
• Weights citations based on the total number of citations in a given field (subject), which allows you to compare journals across subjects.
• Available via Scopus and on CWTS Journal Indicators website.

h-index

• The largest number h such that at least h articles in that publication were cited at least h times each. For example, a publication with five articles cited by, respectively, 17, 9, 6, 3, and 2, has an h-index of 3.
• Google Scholar Metrics uses the h5-index, which is the h-index for articles published in the last 5 complete years.
