3- by 5-inch index cards mentioned above, many law
enforcement agencies have found it desirable to use a separate sheet,
sometimes referred to as a "History Sheet" or "Information Sheet,"
containing the complete case history of the subject involved. These
separate sheets can be filed by fingerprint number sequence and
contain not only the data such as the known aliases, the fingerprint
classification formula, the arrest number, and other essential items
which are set out on the 3- by 5-inch cards as heretofore described,
but also contain a concise summary of the subject's arrest history,
particularly with reference to his criminal activities in the
particular city. They may also contain a summarized case history with
respect to each arrest or commitment, including such items as the date
and place of arrest, complete home address, relatives, the essential
facts concerning the prosecution of charges, and the ultimate
disposition.

_Jacket folder file_

When an identification bureau receives prints of individuals on whom
it already has prints, it is not practical to keep more than one set
of prints per person in what may be called the active fingerprint
file. In these instances the better print should be designated a
"Master" print by having the word "Master" stamped thereon. It should
be given a number, to be known as the master number, which number
should also be placed on all other sets of prints which may be found
to be identical with the "Master" print. The "Master" print is placed
in the active files. The extra prints are placed together in a heavy
folder with their master number stamped thereon. This jacket folder is
then filed in a separate cabinet. Also, if copies of all information
regarding an individual, photographs, and FBI transcript of record are
kept in this folder, his complete record will always be assembled in
an easily accessible unit. The "Master" number should also be placed
on the index card and all the alias cards of the individual. Also,
each new alias and arrest number should be placed on the original
index card. The additional records are kept in folders which are
arranged in numerical order, beginning with Nos. 1, 2, 3, and so on.
