The duty and task for UDC in updation and maintenance lie with the International Federation
for Information and Documentation (FID). The FID however, acts in conjunction with national
firms which are having the consultative arrangements with scheme users. Thus, it is the
Classification Sector of FID which sustains the UDC Master Version integrating all approved
amendments. The scheme is periodically revised. The amendments aimed by users by their
national agencies which are disseminated as P-Notes to subscribers. As soon as they become
acceptable they could either become abridged, enlarged or withdrawn. Thus, it becomes the
duty of the user libraries to work the amendments that are appearing in the periodical so as to

emerging new concepts as well as decimal. UDC has resorted to what is known as a “gap

are left where future expansion is envisaged. Therefore, you can see the vacant numbers in the
notation which are as follows:
142–159.8 in Philosophy and Psychology
365–367 in social welfare
375 in Education
4 the class philology transferred to 8 Literature

Hence, from the above notation, you can examine how UDC has provided for future expansion.
