In March of 2013, we began production of the new JCR data.  Over 55 million cited references were extracted from items indexed in the year 2012.  Over 283,000 lines of algorithms are used to analyze and aggregate these references for the JCR metrics.  

 

10,854 titles appear in the first release of JCR.  The full list of titles is available here.

379 journals will be posting their first Journal Impact Factor this year.  See the list here.

 

The JCR Production team has also prepared information regarding the suppression of journals from the JCR.  A longer post on this subject will follow in the next few days.  In the meanwhile, users concerned about this subject can access information here - click on the link "Learn more about the JCR Suppression Process".

The JCR data are reloaded to accommodate late-receipted journals and a small number of corrections.

In June 2009 we launched a new series of reports aimed at examining the changing landscape of the global research base. Our latest report, Global Research Report: Japan, found that despite its long-standing position as an innovation leader, Japan’s overall national trend points to a comparatively flat research output and declining share of the world’s annual scientific literature.  What is behind this underperformance? And what challenges, or opportunities, are on the horizon?

 

Download the report here then share your thoughts below.

 

Do you see a looming threat to Japan’s prominence, or is there a less ominous reason behind this trend of change? What do you believe may be behind this static performance? And what might Japan’s leaders do to turn this around?

On June 17 the 2009 Journal Citation Reports® (JCR) was released. This edition of JCR includes more regional journals than ever before. And now we want to hear from you! Read more...
