“What is the impact to the h-index: Prior to this release [of content from 1970 to present] the h-index was only calculated using post-1995 publications. Authors that have published work prior to 1996 may now see an increase in their h-index, even though no pre-1996 cited references have been indexed to date. This can be explained by post-1995 citations given to pre-1996 works. An author’s h-index is now calculated with publications as far back as 1970, and their citations from 1996 onwards. For example, an author’s 1993 publication that received citations in 1999 will now be included in the calculation and positively impact the author’s h-index.
No cited references pre-1996 have been added to Scopus.com yet. The first content will start to appear in November 2014.”
