2014 Impact Factor release shows the influence of content published by Portland Press

Biochemical Society

The Impact Factors and journal metrics for the range of molecular bioscience journals published by Portland Press, the knowledge hub for life sciences, have been announced. The 2015 Release of Journal Citation Reports® (Source: 2014 Web of ScienceTM Data) shows an increase in article influence scores indicating that the research being published and cited in Portland Press journals carries influence scores above the average in its field.

The announcement of these metrics comes in the middle of an exciting year for Portland Press. Having just migrated all its journals to new websites offering a range of new features and improved discoverability for authors' work, further developments are planned for the remainder of 2015. System changes will make submitting and publishing with Portland Press easier and the publisher will upgrade to an XML first process. Authors and libraries will be guided through these changes by a publishing team committed to community engagement alongside providing the best possible publishing service to its authors and the best possible customer service to institutions.

Biochemical Journal remains in the top quartile of all journals in the 'Biochemistry and Molecular Biology' category with a very good immediacy index of 0.894 (ahead of several competitors) and an excellent article influence score showing that it is a good place to publish to get cited quickly and influence further research output.

Clinical Science builds on last year's leap with an Impact Factor of 5.598, with a fantastic immediacy index showing how topical and urgent the work published in this journal is. The journal ranks in the top 15 of all titles in the 'Medicine, Research and Experimental' category.

Biochemical Society Transactions retains an Impact Factor of over 3 with an above average article influence score that highlights the relevance of its coverage and the Biochemical Society scientific meetings from which it sources some of its papers.

Each issue of Essays in Biochemistry provides an overview of a topic offering a complete picture of the field. Crucially, the overview is written to be accessible to those not yet immersed in the subject. Given the very topical nature of its coverage, and its differing level of readership, we are delighted that the journal has an above average article influence score, and a steady five-year impact factor of 3.8.

Bioscience Reports maintains a steady Impact Factor of 2.637 and, as a fully Open Access journal, continues to support Portland Press' commitment to open science.

Professor Richard Reece, chair of the Portland Press Board, commented "I am pleased to see these Portland Press journal metrics. This is a vote of confidence from the life sciences community for the coverage of, and content in, our titles."

Dr. Niamh O'Connor, director of publishing at Portland Press said of the metrics "I am delighted that Portland Press journals have maintained their ranking and am especially pleased to look outside the Impact Factor to other metrics such as Immediacy Index and Article Influence Score and see the relevance and influence of the vital content being published in our journals".
