The International Standard offers guidelines for the content, organization and presentation of indexes. It is concerned with basic indexing principles and practice rather than with the detailed procedures that vary according to type of matter indexed and the users for whom the index is intended. It covers the choice, form and arrangement of headings and subheadings used in index entries once the subjects to be indexed have been determined. It is relevant to the preparation of all types of index, produced manually or by computer-assisted methods. The guide provides a interpretation of the standard according to Danish conditions.
