Knowledge Organization: Classification and Cataloguing Theory

Notes Library classification of a piece of work consists of two steps. Firstly, the “aboutness” of
the material is ascertained.

Depending on the size of the library collection, some libraries might use classification
systems solely for one purpose or the other.
In libraries where the collection is arranged by accession number, or author or title, and
not by subject, books on the same subject will be scattered throughout the collection.
Classification helps achieve a systematic arrangement of different types of documents.
In big libraries, the collection is segregated in different sections or departments.

The arrangement of documents on the shelves is in a progressive order of complexity, i.e.,
from the general to the specific.

There are several different types of library classification schemes around, varying in
scope, methodology and other characteristics.
In standardizing the form and layout of documents, it is necessary to restrict this activity
to that which does not affect the spiritual contents and which serves to remove a really
irrational variety.
