The Journal Citation Reports for 2009 are now available. For science, technology and the social sciences JCR sheds some light on which journals are more prestigious in particular fields by giving a variety of citation data for each journal. Thus you can rank journals in a field by how frequently they are cited or by its impact. There’s various bibliometrics available including:
- the impact factor (the average number of times articles from the journal published in the past two years have been cited in the JCR year).
- the immediacy index (the average number of times an article is cited in the year it is published).
This year over 1000 new journals are included. So if you want to know which Limnology journal has the highest impact factor (answer: Limnology and Oceanography with an impact factor of 3.545) or which is the most cited polymer science journal (Macromolecules) then JCR is where you’ll find the info.
