The Aim of this paper is to inform the public about the characteristics of changes in the group for History, in the frame of the 9 Class/Code of UDC Tables. The Composite numbers, for History of some Countries and Nations, have been replaced by the combination of the new number 94, for the General History and common auxiliary numbers, for the place and time, following the logic of the automatic searching. This enables to find various data about one Country (including also the historical data) within one search.
