with the certitude that the Universe of Subjects too would have been thereby attended to

5.5.3 Comparison of CC and UDC
CC can be compared only with UDC. It is like UDC in that it is a Faceted Scheme.
But it differs from UDC in the following respects:
1. CC is a Freely Faceted Classification, whereas UDC is only a Nearly Faceted
Classification;
2. CC starts with a short schedule of Basic Classes, whereas UDC has not yet
escaped from the grip of the rigid DC core and giving a Schedule of
Compound Classes running to several hundred pages;
3. CC is guided by definite objectively applicable principles and the need for
flair is reduced to an enormous extent, whereas UDC still depends a good deal
on subjective decisions instead of objective ones based on stated principles;
4. CC has the advantage of six schedules of Common Isolates and of several
Special Isolates for the Compound Subjects going with the respective Basic
Subjects, whereas UDC has only three distinctive schedules of Common
Isolates and its Schedules of Special Isolates are far too few and they very
much mix up different kinds of isolates;
5. CC has made full use of the advantages of a Mixed Notation, whereas UDC is still
essentially in the grip of Indo-Arabic numerals;
6. In CC, the sequence of the isolates in a schedule, the sequence of facets in a
Compound Subject, and the sequence of the Compound Subjects going with the
respective Basic Subjects conform much more to a common pattern than the
subjects of UDC do;
7. The Canonical Subjects of CC include the various Systems of Development of
each Basic Subject and also the Specials going with each Basic Subject. This
feature is rarely found in UDC; and
8. On account of the large base of its Notational System and provision for any
number of facets that may be determined by the Idea Plane, the average
number of digits in CC numbers is smaller by 50 per cent than the average
number of digits in a UDC Number (66). CC appears to be preferable to UDC.
The members of the Odense Meeting have had no experience in working with
CC. That is why they have not considered it.
6 PLACES FOR NEW SUBJECTS
6.1 Distinction Between Macro Subject and Micro Subject
It is helpful to distinguish between a Macro Subject and a Micro Subject. Till the
end of the nineteenth century, the designers of classification have been confining
themselves to Macro Subjects — that is, subjects whose extension is large enough to need an
