The project plan called for the purchase of an infrared data search system and the use of this system by selected forensic laboratories operating in New York State. The study tested the hypothesis that the availability of a computerized data file could provide the mechanism through which the potential of infrared analysis could be realized within the operating context of a forensic science laboratory. The major goals of the study were to demonstrate the utility of the central computerized data file concept for forensic science laboratories, to provide data to enable the Criminalistics Research Bureau to make recommendations for further development of the central data file concept as applied to forensic science operations, and to provide an immediate computerized data file service for selected forensic science laboratories. The study concluded that the central data file concept for forensic science laboratories is a highly desirable addition to the laboratories' analytical capabilities. Also, the infrared data file search system in its current state of development does assist in infrared data interpretation connected with cases across the full range of forensic problems. Recommendations are offered for the design and implementation of scientific data files for forensic science laboratories. 7 figures and 10 references
