Journal impact factors: Frontiers at the top of citation and impact metrics

2017 journal impact factors: Frontiers at the top of citation and impact metrics

Frontiers journals lead in citations & rank in the top Impact Factor and CiteScore percentiles

Frontiers journals rank among the world’s most-cited in their fields — including top most-cited in neurosciences, microbiology, plant science and psychology. In total, Frontiers articles have received more than 700,000 citations to date.

Our journals also have some of the highest citation rates. Among the world’s 20 largest publishers in 2017, Frontiers ranks 4th most-cited with an average of 3.65 citations per article.

Moreover, within each academic category our journals rank in the top Impact Factor and CiteScore percentiles.

Furthermore, Frontiers articles are highly visible at a global scale. To date, Frontiers articles have been viewed and downloaded more than 420 million times from research and innovation hubs around the the world and mentioned 620,000 times in the news and social media.

All of this is only possible with a stellar editorial board of 80,000 researchers, our diligent and committed Associate and Review Editors, the dedicated Frontiers Journal Development Teams — and the amazing research of the 300,000 authors who have published in our journals, most of whom come from the world’s top 300 universities.

A heartfelt congratulations and thank you to everyone!

What is journal impact?

Journal impact is traditionally measured via the number of citations received by the articles published within the journal. Journal Impact Factor and CiteScore are two indicators of journal quality while the influence of a journal on a field can be gauged by how much research is built on the papers published in the journal, as measured by the total number of citations.

What are article and author impact?

Frontiers additionally provides a wide array of real-time impact metrics that measure the overall performance and reach of articles and authors in an objective and crowd-sourced way. These include views and downloads, citations, social buzz (news and social media mentions, through altmetrics.com data) and visitor demographics like location, seniority and field of interest.

As opposed to journal metrics, article- and author-level metrics indicate the quality and global impact of individual articles, give credit to individual authors and allow article- and author-level comparisons.

What is the Impact Factor and CiteScore?

The Impact Factor is the average number of citations received in the last year to articles published in a journal for the previous two years. It is measured each year by Clarivate Analytics (formerly known as Thomson Reuters) and reported in the Journal Citation Reports (JCR). The 2017-JCR analysis is based on citations in 2017 to articles published in 2015 and 2016.

CiteScore is a similar metric covering titles in Elsevier’s Scopus database. The CiteScore number represents the average citations received in a specific year to articles published in the previous three years. The CiteScore 2017 edition is therefore based on citations in 2017 to articles published in 2014, 2015 and 2016. CiteScore was launched in December 2016 and is released once a year.
