had cultivated an emotional aversion to Colon Classification, without gaining any<br />
experience with it and even without haying read the scheme and the literature which had<br />
grown around it. Das Gupta knew this. He knew also that two librarians had been doing<br />
some propaganda in the matter. He explained this as the reason for his not disclosing the<br />
names of the two schemes to the professors until they made the choice.<br />

In any comparison of Schemes for Classification, clarity and consistency will be<br />

group of subjects - that is, each subject or each subject-complex of any possible degree of<br />
intension - by a unique ordinal number of its own. This is necessary to re-insert, in its<br />
correct place, any book taken out of the shelves or any entry taken out of the classified<br />
part of the catalogue (44, 47). It is believed that there is no difference of opinion on this<br />
today.<br />
Concept of Class Number<br />
The definition of the term 'Classification', given in the preceding section, is<br />
equivalent to the concept that Class Number is a unique translation of the name of a<br />
subject in a natural language into the preferred Classificatory Language of ordinal<br />
numbers. In this view, the system of all the Class Numbers of a Scheme for<br />
Classification, taken together, may be deemed to be a Classificatory Language (55). This
