The word "document" conjures up to most a medium of past or present information, which could be in the form of a clay tablet of antiquity or a modern encyclopaedia. It is justifiable, therefore, to assume that this dictionary encompasses several wide-ranging subjects. The fields covered are also closely related, a fact which can be attributed to the enormous impact of automation and technology. In clarifying various topics, Mr. Clason has listed specific documents - in itself an unusual approach which will do much to assist operational scientists.

Besides these, POPSI, PRECIS and ISBD and chapter on Normative Principles have been elaborated by giving additional examples and comments. The last chapter of the book has been rewritten and renamed as Progress in Library Cataloguing.This book is a special effort to undertake a comparative study of two cataloguing codes: The Anglo American cataloguing rules (1967 and 1978 editions) and Ranganathan’s Classified Catalogue code (1964).

The other special feature of this study is the simplicity in the style of writing.
