Attention is drawn to the inadequacies of the existing classification
schemes as pointed out by individuals and groups concerned with classi
fication research. The article is based on an earlier study by the aut
hor, which identified and arranged in a filiatory way the main concept
s of sociology and determined their relative significance as headings
in a classification scheme The sociology schedule in the Dewey Decimal
Classification was examined on the basis of nine evaluation criteria,
as e.g. arrangement of major categories, provision for main concepts,
use of phrased headings instead of individual key terms, and scatteri
ng of related concepts in the schedule. It was found that a large numb
er of the main concepts of sociology are either not represented in the
schedule or mentioned in the scope note only along with the main head
ings. A table shows one hundred main concepts of sociology arranged an
d classified within ten major categories or sections, and their provis
ion in the DDC. The study suggests that the DDC needs serious reconsid
eration with regard to the main headings/categories provided as class
headings, terminology used for the concepts, the filiatory structure a
dopted, and the representation of the main concepts of sociology.
