[This post is part of an ongoing series about impact factors]

In the world of abused performance metrics, the impact factor is the undisputed heavyweight champion of the (publishing) world.

It has been an eventful year in the boxing ring of scientific publishing since the last set of figures were published by Thomson-Reuters. A brand new journal called PeerJ launched with a radical publish ’til you perish business model [1]. There’s another new journal on the way too in the shape of eLifeSciences – with it’s own significant differences from current publishing models. Then there was the Finch report on Open Access. If that wasn’t enough fun, there’s been the Alternative metrics “Altmetrics” movement gathering pace [2], alongside suggestions that the impact factor may be losing its grip on the supposed “title” [3].

The impact factors below are the most recent, published June 28th 2012, covering data from 2011. Love them or loathe them, use them or abuse them, game them or shame them … here is a tiny selection of impact factors for the 10,675 journals that are tracked in Journal Citation Reports (JCR) ordered by increasing punch power.

WARNING: Abusing these figures can seriously damage your Science – you have been warned! Normal caveats apply, see nature.com/metrics.

* The Russian Journal of Cardiology is included here for reference as it has the lowest non-zero impact factor of any science journal. A rather dubious honour…

** The Cancer Journal for Clinicians is the highest ranked journal in science, it is included here for reference. Could it be the first journal to have an impact factor of more than 100?

  1. […] Impact factors are a measure of a journals ‘impact’ on a field and therefore marks the prestige of the papers published within them. Impact factors range from 0.5 and below for bad journals to 1.5-4 for good HCI journals, to 30-36 for the likes of ‘nature’ and ‘science’ with the top rated journal in the world being ‘CA – A Cancer Journal for Clinicians’ with 101. You can find a more ‘Bio’ view on these with O’Really’s Impact Factor Boxing… […]
