Over the past few months there have been a number of discussions in the blogosphere about the future importance and value of classical Impact factors but for now they remain the industries primary measure of, well Impact. With that in mind it was good to see this announcement from the RSC regarding recently published impact factors for Chemistry related journals. Nice…it’s good to know that we joined an organization that continues to focus on its core mission and strengths and be acknowledged by the readers and the industry for its efforts.

25 June 2009
Publication of the 2008 impact factors, calculated by ISI, once again brought good news for authors and readers of RSC journals. 

Nearly all the RSC journals increased in impact factor, immediacy index and article influence, with an impressive average impact factor increase of 8.2%. Overall, the average impact factor for the RSC portfolio now stands at 4.7, equal to that of the ACS collection. 

RSC journals feature in the top 10 rankings (by impact factor and immediacy index) in 6 of the 7 core chemistry categories* as listed on ISI, and of the top 100 chemistry journals, ranked by impact factor, 15 are from RSC Publishing. 

Three individual journals to highlight include: 

ChemSocRev – with a 33% increase, its impact factor now stands at 17.419, confirming its position as a leading international chemistry journal. This flagship journal now contains the greatest number of chemical reviews published in 2008 of any chemistry review journal – making it truly, first in its class. 

Lab on a Chip – celebrates a 28% rise taking its impact factor to 6.48, placing it within the top ten journals in the multidisciplinary chemistry category. 

PCCP – rises over 20% to its highest ever value of 4.06. Additionally, its new immediacy index (0.81) remains the highest value for any journal publishing general primary research in the fields of physical chemistry and chemical physics. 

Editorial Director, Dr James Milne, reflected on the outstanding performance of the RSC journals, ‘the impressive increases in impact factor for the RSC portfolio of journals are a direct reflection on the world class authors who regularly publish in these prestigious international titles. Over the last five years, RSC journals have attracted a significant increase in submissions, with nearly 60% more material published during this same short period.’ He continues, ‘to provide more articles and also higher quality articles, is a clear reflection of the dedicated support the journals receive from authors, editors and referees throughout the world; for this contribution, I would like to sincerely thank all the scientists involved.’

RSC is committed to providing a world-class publishing service to its authors, and to deliver cutting-edge chemical science to researchers throughout the world. The rise in citations, impact factors and immediacy indices provide a clear indication that more researchers than ever before are recognising journals from the RSC as a key resource to access the very best research.

Journals from RSC Publishing provide exceptional value for money, with high impact science, investment in award-winning technologies and flexible pricing models. To add RSC Journals to your collection, please contact our Sales team via the form below.

The Impact Factor provides an indication of the average number of citations per paper. Produced annually by ISI®, Impact Factors are calculated by dividing the number of citations in a year, by the number of citeable articles published in the preceding two years.

The immediacy index is a measure of how topical and urgent the papers published by a journal are. It is calculated by dividing the number of citations to articles published in a given year by the number of articles published in that year.

Data based on 2008 Impact Factors, calculated by ISI®, released June 2009.
