Thanks Dear Najim. Which Agency is given this rating?

Dr. Md. Zukhrufuz Zaman has answer your query.

Thanks both of you dear

JCR is one of the best websites; however you have access to that from your institute.

the following website is free and you can get IF:

http://www.bioxbio.com/if/

enter the name of your journal, then in the new window, follow the links to see the IF.

Thanks Dear Rasoul

Check also http://www.scopus.com/home.url and http://apps.webofknowledge.com

Thanks to all for your valuable suggestions

To clarify - it is the 2012 Impact factor that has just been released rather than the 2013. It is always a year behind

Thomson Reuter's, Journal Citation Reports is the mechanism that calculates and publishes these.

Thanks Paul

@Devang - as per my previous post, the JCR is always 1 year behind so the 2012 IF is the latest figure released in June 2013.

You can also refer to this link https://www.hsl.virginia.edu/services/howdoi/hdi-jcr.cfm

Check the IF on the Journal home page. Usually you can find it.

how to check the impact factor for a Scopus Indexed journal

The Impact Factor for a journal is generally calculated based on fixed time period. It is generally 3 year period. It is mean of number of number of times the papers published in that journal are referred.

For example If the year of publication is 2014 then the ratio of the number of times articles published in 2012 are referred in standard journals in 2014 and the number of published papers during 2012 is called impact factor.

This is complete official list. It does not tell impact factor. But all indexed journals are listed here.
