In response to a request for technical assistance, a study was made of the Colorado Bureau of Investigation, Criminal Identification Section's (CIS) manual fingerprint and jacket files.
Abstract
The technical history of the CIS is presented, emphasizing its advanced state of computer technology with namesearch and computer assisted technical search capabilities. The process of source documents through CIS is traced through computerized and manual namesearch procedures and through computerized fingerprint technical search with provisions for updating the computer files by the technician. Concerns with the manual fingerprint and jacket files center on their use of floor space and on their substantial labor cost (for use and maintenance). An analysis is made of alternatives to the manual files, and recommendations include replacing them with strip microfilm in cartridges, in either 16 mm or 35 mm, in either positive or negative mode. Futher analysis deals with costs and weight reduction. Findings show large weight reduction, higher accuracy rates and a faster verification process resulting in lower operating costs. Specific recommendations for the implementation of the microfilm master fingerprint file and the microfilm jacket file concern subjects, source documents use, work stations, record format, modification of the computerized namesearch routine and the technical search method, and an action plan by season for the coming year.
