ISO 999:1996

Overview

ISO 999:1996 - Information and documentation - Guidelines for the content, organization and presentation of indexes is an international standard developed by ISO. This essential document provides comprehensive guidelines for creating, organizing, and presenting indexes for a wide range of sources, including books, periodicals, reports, patent documents, and an expanding variety of non-print materials such as electronic documents, films, sound recordings, and video recordings.

Adhering to ISO 999:1996 helps ensure that indexes serve as effective tools for locating information, supporting better access and retrieval for all information users. By standardizing indexing practices, ISO 999:1996 promotes consistency, clarity, and usability across diverse formats and subject domains.

Key Topics

• Purpose and function of indexes: The standard describes core indexing principles, emphasizing the index’s role in providing an efficient pathway for users to trace and access information within documents or collections.
• Types of indexes: ISO 999:1996 covers subject, author, name, geographic, title, and numerical/code indexes, as well as their arrangement and appropriate use.
• Content and structure of entries: Guidelines include the selection, form, and hierarchy of headings and subheadings, ensuring that index entries are logical, specific, and helpful to users.
• Authority files and terminology: The standard underscores the use of authority files and standardized terminologies to improve consistency-an essential element for ensuring high-quality, user-friendly indexes.
• Quality control: Recommendations on maintaining quality, balancing index length and detail, ensuring consistency, and effective collaboration between indexers, authors, and publishers.
• Presentation and layout: Guidance is given for both printed and electronic indexes, including entry arrangement (e.g., alphabetization methods), typographic conventions, use of cross-references, and distinction between indented and run-on styles.
• Special considerations for different media: While focused on basic indexing principles, the standard’s recommendations remain relevant regardless of whether indexes are created manually or via computer-assisted methods.

Applications

Implementing ISO 999:1996 is valuable for organizations, publishers, librarians, archivists, and information professionals engaged in the development and maintenance of indexes. Practical applications include:

• Publishing: Ensuring books, academic journals, and technical reports feature well-constructed, user-friendly indexes.
• Digital content management: Supporting the indexing of electronic documents, multimedia, and databases for optimized information retrieval.
• Patent and legal documentation: Facilitating efficient access to complex technical and regulatory documents.
• Libraries and archives: Enhancing cataloging and resource discovery, excepting specialized catalogues for libraries and museums, which are outside the scope.
• Corporate and institutional knowledge management: Streamlining documentation access within varied business and research environments.

Applying ISO 999:1996 improves both the creation process and the user experience, making information significantly more discoverable and navigable.
