Journal Citation Reports (JCR) Releases New Data
The Library is pleased to announce the availability of the 2007 ISI Journal Citation Report. The JCR tracks 7,600 of the most important journals in the sciences and social sciences. With the data provided, researchers can use the JCR to help determine the most influential journals in their disciplines and which journals they should read.
The JCR uses the following metrics; it ranks journals in a given field by the number of articles published, the number of times that articles from the journal are cited in the report year, the immediacy factor - which is the average number of times articles are cited within the same year of publication - and finally, the impact factor, the number of citations from the current year to articles published in the journal over the past two years. The report also provides the frequency with which journals in related fields cite each other. The Library’s subscription to JCR Online includes reports from 1998 to 2007, and the Library also owns earlier issues in paper and microfilm. The reports covering 1990 to 2002 are available on reserve at the Science Library .
