Federal Bureau of Identification in Leavenworth, Kansas, for example, it was necessary to extend the Henry system, by creating further subdivisions, as early as 1919 [83]. Many other bureaus had to extend their existing manual classifications systems with further subclassifications. Although extending classification systems kept files manageable for the purposes of verifying criminal histories (that is, 10-print to 10-print comparisons), the more fingerprint files expanded, the less useful they were for forensic identification.
