the necessity of a universal system of weights and
measures. In 1895 the first International Conference
of Bibliography chose the Decimal Classification
and adopted a complete plan for its development. In
1904, the edition of the expanded tables appeared. A
new edition was being prepared when the war broke

In its latest state, the Decimal Classification has

treatises. But, as it would be impossible to find a
particular subject’s relative place by reference to
another subject, a system of numbering is needed.
This is decimal, which an example will make clear.
Optical Physiology would be classified thus:

5th Division
7th Sub-division

or 535.7
This number 535.7 is called decimal because all
knowledge is taken as one of which each science is
a fraction and each individual subject is a decimal
subdivided to a lesser or greater degree. For the sake
of abbreviation, the zero of the complete number,
which would be 0.5357, has been suppressed because
the zero would be repeated in front of each

The classification is also called decimal because
all subjects are divided into ten classes, then each
of these into at least ten groups, and each group
into at least ten divisions. All that is needed for the
