Journal Citation Reports^�

The Institute for Scientific Information^� (ISI^�) publishes the Journal Citation Reports (JCR^�), which provides a systematic and objective means of determining the relative importance of science and social sciences journals within their subject categories.

Citation data offer a unique view of primary research journals, one that is objective and quantifiable. Because only ISI includes the cited references of every article it indexes, only ISI can provide such valuable information.

What the JCR Tells You

With the JCR, you will be able to answer many important questions about the current literature, such as:

What journals are most frequently cited? The JCR ranks journals by the number of times they are cited in a given year; providing an international assessment of journals by scholars who have responded to the items published.

What journals have the highest impact? The JCR reports the average number of cites that recently published articles in a journal receive in a given year; revealing relative importance among journals, especially those in the same or similar fields.

What are the hottest journals? The JCR reports the average number of times a journal's current articles are cited in the same year they are published (Immediacy Index), indicating journals that are publishing the latest research in fast-moving specialties.

What are the largest journals? The JCR conveniently ranks journals by the number of articles published in the current year; enabling users to review journal size and track trends within particular specialties.
