We evaluate only Journals that are live and active. The publisher must provide full access to last 3 issues and consecutive current issues, as they are published, to IJIF, throughout the evaluation process until a decision is made. A minimum of three consecutive current issues will need to be evaluated. The issues provided should reflect the journal’s version of record. This refers to the most complete and authoritative version of the publication — be it electronic or print.
In the evaluation and rating process we consider various parameters(not limited to):
1. We consider citations in publications including textbooks, handbooks and reference books along with journals.
2. Self-Citing is also considered (But points awarded will be 1/4 th of normal citation)
3. Current industry practices have electronic formats provided to us more often than print. But we give additional points for Print journals.
4. Print journals with good subscription base are awarded additional points.
5. Only Journals with ISSN numbers (Print or Online) are considered for evaluation.
6. Online Journals should be open access and Peer Reviewed.
7. Should publish Issues on a regular basis.
The impact factor (IF) of an academic journal is a measure reflecting the average number of citations to recent articles published in the journal. It is frequently used as a proxy for the relative importance of a journal within its field, with journals with higher impact factors deemed to be more important than those with lower ones.
Calculation
In any given year, the impact factor of a journal is the average number of citations received per paper published in that journal during the two preceding years. For example, if a journal has an impact factor of 3 in 2008, then its papers published in 2006 and 2007 received 3 citations each on average in 2008. The 2008 impact factor of a journal would be calculated as follows:
A = the number of times that articles published in that journal in 2006 and 2007, were cited by articles in indexed journals during 2008.
B = the total number of “citable items” published by that journal in 2006 and 2007. (“Citable items” are usually articles, reviews, proceedings, or notes; not editorials or letters to the editor.)
2008 impact factor = A/B.
(Note that 2008 impact factors are actually published in 2009; they cannot be calculated until all of the 2008 publications have been processed by the indexing agency.)
New journals, which are indexed from their first published issue, will receive an impact factor after two years of indexing; in this case, the citations to the year prior to Volume 1, and the number of articles published in the year prior to Volume 1 are known zero values. Journals that are indexed starting with a volume other than the first volume will not get an impact factor until they have been indexed for three years. Annuals and other irregular publications sometimes publish no items in a particular year, affecting the count. The impact factor relates to a specific time period; it is possible to calculate it for any desired period, and the Journal Citation Reports (JCR) also includes a five-year impact factor. The JCR shows rankings of journals by impact factor, if desired by discipline, such as organic chemistry or psychiatry.
