In 2012, the National Institute of Standards and Technology (NIST) Forensic Science Research Program, with sponsorship from the National Institute of Justice (NIJ), focused to develop a comprehensive list of databases, reference materials, and standard reference collections used by forensic scientists in laboratories at the state and local levels. The main goals were to identify existing data for forensic practitioners and to discover prevailing limitations. The results of the search identified 228 state, federal, and commercially run databases which are all available to view at: http://www.nist.gov/oles/forensics/forensic-database.cfm
Since then, NIST has been involved in several efforts to assist in expanding the availability of data and reference materials for various disciplines including biometrics and firearms. On July 19-20, 2016, NIST will hold an event titled; "Trace Evidence Data Workshop: Improving Technology and Measurement in Forensic Science." This event is a part of an effort at NIST to gather feedback from the practitioners and researchers in the forensic science community on further improving access and expanding the development of datasets useful for trace forensic evidence.
