Wolters Kluwer Health has announced that seven of its Lippincott journals have been ranked #1 based on their 2017 Journal Citation Report (JCR) Impact Factor Score from Clarivate Analytics.

Lippincott holds 21 Top 5 spots across 14 specialties and 44 Top 10 across 25 specialties. Rounding out the top 20 rankings, Lippincott holds 90 spots across 39 specialties.

New integration provides a record of scholarly references for over 11 million research publications
- 31 Jul 2018

Alternative metrics provider Altmetric has added citation data from research insights platform Dimensions to all of its tools and services, providing extensive visibility of where and to what extent scholarly publications have been cited by other academic works.

Part of technology company Digital Science, Altmetric collects online mentions relating to published research to make it possible for authors, publishers, institutions and funders to more easily identify and monitor the academic and broader influence of their work.

The openly-available Dimensions citation data joins mentions from sources such as the mainstream media, patents and policy makers on Altmetric details pages, which provide a complete record of all of the online attention found for an item.

Along with a count of total citations, the top 3 most recent citing publications are now listed in a new tab on Altmetric details pages. The details pages can be accessed by clicking on the Altmetric badges where they appear on publisher sites and institutional repositories, or within the Altmetric Explorer platform, where users can now sort search results by citation counts and export the data for further analyses.

The Dimensions citation data are live now in the Altmetric Explorer and details pages.

New analysis reveals OA journals have clear citation advantage over subscription journals
- 13 Jul 2018

Open-access scholarly publisher Frontiers is the 4th most cited publisher amongst the 20 largest publishers, ranked by average citations over a three-year period (2015-2017). The same analysis also reveals a citation advantage of Open Access journals over subscription journals in the last three years.

In 2017, 16 percent of peer-reviewed papers worldwide were published in fully Open Access journals, according to SCImago (2018). After over two decades of the Open Access revolution, this is a far cry from the aspired 100 percent. One of the many reasons why the transition to Open Access turned out to be so difficult is the debate whether Open Access can produce scientific excellence.

In 2017, four of the 20 largest publishers are full Open Access publishers, 16 are traditional subscription publishers with a range of subscription, hybrid and fully open access journals.

The average citations over a three-year period (2015-2017) amongst the largest 20 publishers, the performance of fully Open Access publishers is remarkable.

Frontiers' average citation rate is 3.65 per paper and well above the average of 2.7 for subscription journals and 2.9 for Open Access journals. Amongst the ranked publishers, only Learned Societies specialising in a single, highly-cited field, such as chemistry or physics, rank higher. Among multidisciplinary publishers, Frontiers has the highest average citation rate.

Other fully Open Access publishers also rank above average on citation rates: PLOS ranks 6th with an average citation rate of 3.25 and MDPI 8th with an average citation rate of 3.10.

Across the last three years, Open Access journals received on average 7 percent more citations than subscription journals. Open Access journals published by traditional subscription publishers are generally achieving more impact within the same publisher.

In the open access and subscription journals break out by those 20 publishers, Open Access journals see a citation advantage, with an average of 2.9 citations per paper for Open Access journals versus 2.7 citations per paper for subscription/hybrid journals.

While 10 out of the 16 traditional publishers show a clear citation advantage for their Open Access journals, there are some variations, likely reflecting different strategies with the titles, as well as a publisher's standing in terms of the content they attract.

These findings are in line with a recent White Paper published by Springer Nature and Digital Science, which demonstrated a clear citation advantage of Open Access articles over paywalled articles in hybrid subscription journals. Articles published in the Open Access format were 1.6 times more cited than paywalled articles within the same journals.

- 12 Jul 2018

Wiley's performance in the 2018 release of Clarivate Analytics' Journal Citation Reports (JCR) remains strong, maintaining its position as #3 in terms of the number of titles indexed, articles published, and citations received. Wiley saw a 9.5 percent increase in JCR articles, giving it 9.7 percent overall share (+0.6 percent) - its biggest increase since 2008.

Overall, 1,223 Wiley journals were included in the reports, 58 percent of these were society publications - reaffirming Wiley's position as the leading society publishing partner. Wiley journals ranked #1 in 27 categories across 25 titles and achieved 349 top-10 category rankings.

The annual Journal Citation Reports (JCR) are one of the most widely-used sources of citation metrics used to analyse the performance of peer-reviewed journals. The most famous of these metrics, the Impact Factor, is based on the frequency with which an average article is cited in the JCR report year. Alongside other metrics, this makes it an important tool for evaluating a journal's impact on ongoing research.

In Health Sciences, five journals are ranked #1 in their category: Addiction, CA: A Cancer Journal for Clinicians, Journal of Cachexia Sarcopenia and Muscle, Periodontology 2000, and World Psychiatry. CA: A Cancer Journal for Clinicians retained its #1 spot across the entire JCR and its Impact Factor increased to 244.585. World Psychiatry also retains its #1 rank in the Social Science Citation Index, increasing its Impact Factor to 30.000. 70 titles achieved top 10 category rankings and International Journal of Older People Nursing received its first Impact Factor.

In Social Sciences, nearly 350 titles appeared in the 2018 JCR. Of these, seven journals are ranked #1: American Journal of Political Science, Econometrica, Journal of Child Psychology and Psychiatry, Journal of Finance, Population and Development Review, Public Administration Review, and Social Issues and Policy Review. 71 titles ranked in the top 10 of their category and four titles received their first Impact Factor: Presidential Studies Quarterly, Sociology Compass, PsyCh Journal and Geography Compass. Statistics in Medicine remains the top cited journal in Medical Informatics with over 23,000 citations, twice that of the next title.

In Physical Sciences, Advanced Materials Technologies (4.622) received its first Impact Factor and ChemistrySelect (1.505) its first-half Impact Factor. Wiley journals continued to lead within their subject categories and 46 titles achieved top 10 category rankings. Six titles ranked #1 in their category including International Journal of Energy Research, Mass Spectrometry Reviews and Acta Crystallographica Section C Structural Chemistry. WIREs Computational Molecular Science held its #1 position for the fourth straight year and Computer-Aided Civil and Infrastructure Engineering topped two categories.

In Life Sciences, Food Science and Nutrition (1.521), Molecular Genetics&Genomic Medicine (2.695), and WIREs Water (3.943) received their first Impact Factor. There are 85 journals in the Top 10 for their subject category within the Life Sciences, notably WIREs Water achieved a top ten rank with its first Impact Factor. Eight titles ranked #1 in their fields including Reviews in Aquaculture, The Palaeontology Society's flagship journal Palaeontology, Global Change Biology, and Global Biology Change Bioenergy.
