The Science Citation Index Expanded (previously titled Science Citation Index) is a citation index originally produced by the Institute for Scientific Information and created by Eugene Garfield. The Science Citation Index (SCI) was officially launched in 1964, [1] and later was distributed via CD/DVD. [2]
To access SCI, one must first have a favorable SSBI and be granted SCI eligibility. Because the SSBI is also used to grant collateral top secret eligibility, the two are often granted together and referred to as TS/SCI. Access to individual SCI control systems, compartments, and subcompartments may then be granted by the owner of that information.

SAP and SCI implementation are roughly equivalent, and it is reasonable to discuss their implementation as one topic. For example, SAP material needs to be stored and used in a facility much like the SCIF described below. Department of Energy information, especially the more sensitive SIGMA categories, may be treated as SAP or SCI.
