The Science Citation Index.

Two recent comments have discussed the problems of assuring relative completeness in the conduct of a literature search (see records 1990-56978-001 and 1990-58219-001). Both letters failed to mention the Science Citation Index, which can be found in most major university libraries. The SCI lists for any particular source article all or nearly all subsequent papers that have cited or referenced the source. All older references used in recent periodicals are included. The use of the SCI in conjunction with the hierarchal search procedure suggested by Goldsamt would seem to be an obvious advantage. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
