Fingerprint Files
It is suggested that the fingerprint card be white, light cardboard, 8
by 8 inches, slightly glazed. This size is convenient, as it allows
all the space necessary for recording the classification of the prints
and general descriptive information concerning the individual. In the
event the new bureau desires to contribute copies of its fingerprints
to the Federal Bureau of Investigation, the latter will, upon request,
g
envelopes and instructions on how to take fingerprints. It is
suggested that the new bureau design its cards similar to those
furnished by the Federal Bureau of Investigation, as these have been
designed after special study and have been found to be satisfactory
over a long period of time. Figures 409 and 410 show the fingerprint
side and reverse side of the criminal fingerprint card used by the
Federal Bureau of Investigation.
In classifying and comparing fingerprints it is necessary to use a
magnifying or fingerprint glass. Such instruments can be obtained from
various commercial sources. Figure 411 shows the type of magnifying
glass used by the Federal Bureau of Investigation.
[Illustration: 408. Diagram of a FINGERPRINT INKING STAND]
The fingerprint cards should be filed according to fingerprint
classification sequence in cabinets, preferably steel. It is further
suggested that the cabinets be three drawers high, with each drawer
divided into three rows for filing. Such cabinets or similar ones can
be obtained from various commercial sources. Figure 412 shows the type
of fingerprint cabinet used in the Federal Bureau of Investigation.
In order to facilitate the location of classification groups, it is
suggested that guide cards be placed in the rows of fingerprint cards
at frequent intervals. These guide cards should be slightly longer
and heavier than the fingerprint cards and should have small tabs on
the top to hold classification identifying symbols. Figure 413 shows
the type of guide card used by the Federal Bureau of Investigation.

A practice which has been of the utmost benefit in the Federal Bureau
of Investigation is as follows: When a fingerprint card is taken out
of its regular file for any reason, a substitute card is put in its
place, to remain until the return of the card. This substitute card,
or charge-out card, is of a different color from the fingerprint
card and slightly longer. On it are recorded the name, the
classification formula, and peculiar characteristics, such as scars
and peculiar pattern formations, appearing on the original card. By
indicating the date and reason for charging out the original card, the
Bureau is able to keep an accurate check on the whereabouts of all
prints at all times. It is suggested that the local bureaus adopt a
practice of this kind whenever a fingerprint card is drawn from the
files and it is known that it may be out for a period of time longer
than the remainder of the day on which it is drawn. Figure 414 shows
the type of charge-out card used in the FBI.

Each fingerprint card handled by the bureau should receive a
fingerprint number and these numbers can be assigned in consecutive
order.
As the bureau increases in size, it will be found a source of much
convenience to have fingerprints of males and females kept in separate
files.
