I have seen that some journals go through changes, e.g. slightly change in aims and scope and partial changes of name. For example, beginning in 2014, The Auk will become The Auk: Ornithological Advances. How does this affect impact factor?
Hi, I think this will anser your question:
Journal Impact Factor is from Journal Citation Report (JCR), a product of Thomson ISI (Institute for Scientific Information). JCR provides quantitative tools for evaluating journals. The impact factor is one of these; it is a measure of the frequency with which the "average article" in a journal has been cited in a given period of time.
The impact factor for a journal is calculated based on a three-year period, and can be considered to be the average number of times published papers are cited up to two years after publication. For example, the impact factor 2014 for a journal would be calculated as follows:
A = the number of times articles published in 2012-2013 were cited in indexed journals during 2014
B = the number of articles, reviews, proceedings or notes published in 2012-2013
impact factor 2014 = A/B
(note that the impact factor 2013 will be published in 2014, because it could not be calculated until all of the 2013 publications had been received. Impact factor 2014 will be published in 2015)!
The "new" journal "The Auk: Ornithological Advances" will have a new IF in 2015!
Cheers, Nadine
Thanks. I should have realized that the information could be found at Thomson ISI web page...
