Abstracting & Indexing
A dedicated Science and Technology Development Journal indexing team is working to include all of our journals in reputed indexing services or journal evaluation services. As a result, within a short span of time our journals have been included in some major indexing databases or journal evaluation services and the number is increasing every month.
ISI Impact factor
No new journal, even published by the top most publishers, can have ISI impact factor in first two years of operation. As per the rules of ISI, any new journal may get its first impact factor after two years of operation (See more information in this regard at theofficial web page of ISI or in wikipedia).
The impact factor of a journal reflects the frequency with which the journal’s articles are cited in the scientific literature. It is derived by dividing the number of citations in year 3 to any items published in the journal in years 1 and 2 by the number of substantive articles published in that journal in years 1 and 2
The 2008 impact factor of a journal would be calculated as follows:
A = the number of times articles published in 2006 and 2007 were cited by 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 will sometimes publish no items in a particular year, affecting the count.
