(27 March 2014, Amsterdam) Elsevier’s Scopus has launched its Cited References Expansion Program to include cited references in its database going back to 1970 for pre-1996 content.
In addition to increasing the depth of Scopus’ scholarly content, including cited references for pre-1996 content will make citation data more accurate, therefore expanding the ability for users to perform long-term, extensive bibliometric and historic trend analyses. Moreover, author profiles and h-index counts of researchers who published articles prior to 1996 will be more complete.
