Although the authors do not object to the use of the word ‘Documentation’ in the name of the International Federation for Documentation, nevertheless they claim that this term has not found application in the USSR and indeed they apologize for spending some time in discussing its suitability as a name for ‘the new scientific discipline which studies the structure and properties of scientific information as well as the regularities of scientific information activity, its theory, history, methods, and organization’.
