On June 17 the 2009 Journal Citation Reports® (JCR) was released. This edition of JCR includes more regional journals than ever before. The 2009 JCR provides:

• More than 9,100 of the world's most highly cited, peer-reviewed journals
• More than 850 regional journals included as part of our Regional Content Expansion initiative
• 1,055 journals with their first published Journal Impact Factor
• Journals from over 2,200 publishers in 230 disciplines, from 78 countries
• Features that enhance your understanding of a journal’s influence such as Five Year Impact Factors and EigenfactorTM Metrics, Rank-in-Category Tables, Journal self-citations, and Impact Factor boxplots 

We want to hear from you!

How are you using the metrics that were introduced last year, such as the Five-Year Impact Factor and the Eigenfactor™ Metrics? What new information do these metrics provide you with or how do you use them to gain a more complete view of a journal’s place in the world?

And what about the inclusion of more regional journals? Do these journal metrics help you monitor significant regional studies more effectively? Will they change the way you view journals within their subject category?

@joeydino2

You can view Journal Impact Factors within the Journal Citation Reports interface. Are you a customer?

Journal Impact Factors are part of the Journal Citation Reports, a web-only subscription product from Thomson Reuters.  If your institution subscribes, you should be able to access the product using Web of Knowledge:  www.isiknowledge.com

Check with your librarian to see if your institution subscribes.

Hi,

I Searched the web for Journals and e-journals' JCR in architecture and Animal Science field, but it was not satisfied me at all.

Would you mind send the exact URL for them?

And also, what is the JCR of the journal linked at below URL?

@Fania_h76  The Journal Citation Reports is part of the Web of Knowledge portal of information resources. If your institution has subscribed, you should be able to access the product at:  www.isiknowledge.com under the "Additional Resources" tab. 

   The JCR has Science and Social Sciences editions and these will contain the citation performance metrics for journals covered in Science Citation Index-Expanded and Social Sciences Citation Index, respectively. 

   Architecture journals are included in the Arts & Humanities Citation Index for which we do not produce a formal Journal Citation Reports.

We observe the upcoming 2010 SCI impact factor of the International Journal of Cardiology, a third-rate cardiovascular journal, is likely to be more than 6.  

With regard to this strange phenomenon, we found the international journal of cardiology improves its impact factor by an improper way. We would like to explain this as follows:

The JCR provides quantitative tools (impact factor) for ranking, evaluating, categorizing, and comparing journals. The impact factor of a journal is calculated by dividing the number of current year citations (numbers of citations of all document types published during the previous two years including article, review, letter, editorial, etc.) to the source items (numbers of only 2 document types [article or review]) published in that journal during the previous two years.

Calculation for journal impact factor. 

A= number of 2010 cites to all items (including article, review, letter, editorial, etc.) published in 2008-2009

B= number of items (only the article and review type) published in 2008-2009

C= A/B = 2010 impact factor

We performed the search work using the ISI Knowledge system in Jan 23, 2011.

For the International Journal of Cardiology

2010 cites to all items published in 2008-2009 were 3395.

    Among them,  2010 cites to article/reviews published in 2008-2009 were only 1495,

                   2010 cites to letters published in 2008-2009 were 938,

                   2010 cites to a special editorial published in 2008-2009 were 894, (This editorial entitled "Ethical authorship and publishing" (2009;131(2):149-150), which introduced the Principles of Ethical Publishing in the International Journal of Cardiology, was asked to be cited by all articles in the Guide for Authors of the International Journal of Cardiology. Thus, all the 894 cites were self-citing)

                   2010 cites to other items published in 2008-2009 were 68.

All items published in 2008-2009 were 1889 (not including the meeting abstract).

    Among them,  the number of article/reviews were only 644,

                   the number of letters were 1183, (Among them, only 26 letters were traditional corresponding letters to the editor commenting the previously published article or the reply, and other 1157 letters were actually research article but published as the type of ‘letter’ [‘pseudo-letter’ articles].)

                   the number of other items were 62.

The predicted value of 2010 impact factor = 2010 cites to all items published in 2008-2009/ number of article or review published in 2008-2009 = 3395/644 = 5.27

However, the actual cites per article or review = (2010 cites to article or review published in 2008-2009 + 2010 cites to ‘pseudo-letter’ articles published in 2008-2009 / (number of article or review published in 2008-2009 + number of ‘pseudo-letter’ articles published in 2008-2009) = (1495 + 938)/(644 + 1157) = 1.35 (the actual value reflecting academic influence)

By the improper means, the International Journal of Cardiology increases its 2010 impact factor from 1.35 to 5.27.

For the American Journal of Cardiology

2010 cites to all items published in 2008-2009 were 4337.

    Among them,  2010 cites to article/reviews published in 2008-2009 were 4150,

                   2010 cites to letters published in 2008-2009 were 32,

                   2010 cites to other items published in 2008-2009 were 155.

All items published in 2008-2009 were 1524 (not including the meeting abstract).

    Among them,  the number of article/reviews were 1300,

                   the number of letters were 115, (All the letters were traditional corresponding letters to the editor commenting the previously published article or the reply)

                   the number of other items were 109.

The predicted value of 2010 impact factor = 2010 cites to all items published in 2008-2009/ number of article/reviews published in 2008-2009 = 4337/1300 = 3.34

However, the actual cites per article/reviews = (2010 cites to article or review published in 2008-2009 + 2010 cites to ‘pseudo-letter’ articles published in 2008-2009 / (number of article or review published in 2008-2009 + number of ‘pseudo-letter’ articles published in 2008-2009) = (4150+0) / (1300+0) = 3.19 (the actual value reflecting academic influence)

Thus, we believe the 2010 impact factor of the American Journal of Cardiology, HEART, American  Heart Journal, etc. will be exceeded by the International Journal of Cardiology (3.34 for AJC vs. 5.27 for IJC). However, the actual academic influence of the these journals is far more than the International Journal of Cardiology (3.19 for AJC vs. 1.35 for IJC).

I am interested in your inclusion of more regional journals, particularly European journals. However, I was disappointed not to see our excellent journal 'Ulster Medical Journal' listed there.

We certainly were included in the Impact Factors listing up until 2000, but  appear to have been dropped!! 

The Ulster Medical Journal l has been published continuously since the 1930s. We maintain the highest of standards and our rejection rate is high  All of our back issues are freely available on PubMedCentral.

Question is, do you have impact factors on us? If not, how do we put ourselves on the Impact Factor map?? 

Thanking you in advance. 

Subeditor, Ulster Medical Journal.

How can I get a copy of the 2009 JCR. Any Assistance?
