Overview
ISO 4:1997 - Information and documentation - Rules for the abbreviation of title words and titles of publications - defines internationally accepted rules for creating unambiguous title word abbreviations and title abbreviations for serials and, where appropriate, non‑serial publications. It covers languages using the Latin, Cyrillic and Greek alphabets and serves as the basis for the ISSN Network’s standardized lists of abbreviated title words. ISO 4 promotes unique, consistent abbreviations for bibliographic citations, references, indexing and abstracting services.
Key topics and technical requirements
- Scope and purpose: Rules apply to serials (and some non‑serials) in Latin/Cyrillic/Greek scripts and underpin ISSN title‑abbreviation lists.
- Primary methods: Truncation is the recommended method; contraction (vowel suppression) is allowed. At least two letters must be dropped when abbreviating.
- Punctuation and markers: A full stop (period) indicates a word abbreviation (may be omitted in some applications). Commas in full titles are omitted in abbreviations; full stops may be replaced by commas between title elements.
- Diacritics & transliteration: Diacritic marks are retained in abbreviations; words in non‑Latin alphabets must be transliterated using appropriate international transliteration standards before abbreviation.
- Uniqueness principle: Each title should have a unique abbreviation; the standard encourages use with a standardized list to avoid duplicates.
- Words omitted or retained: Articles, conjunctions and prepositions are generally omitted (except when integral to names or required by national practice). Single‑word titles are not abbreviated.
- Compound terms & names: Components of compound words are abbreviated (hyphens retained). Personal names are not abbreviated; adjectival forms derived from names may be shortened. Corporate bodies may be abbreviated or represented by commonly used acronyms.
- Special characters: Most special characters are retained; the ampersand (&) and plus (+) are omitted when used as “and” (unless integral to an acronym).
Applications and who uses it
ISO 4 is essential for:
- Librarians and cataloguers creating consistent bibliographic records and serials catalogs.
- Publishers, editors and authors preparing reference lists, footnotes and journal abbreviations.
- Abstracting and indexing services (databases, citation indexes) that require standardized title abbreviations.
- ISSN centres and information professionals maintaining title‑word abbreviation lists.
Practical benefits include improved searchability, consistency across multilingual bibliographic data, and reduced ambiguity in citations.
Related standards
- ISO/TC 46 (Information and documentation) developed the standard; related normative references cited in ISO 4 include ISO 1087:1990 (terminology) and ISO 5127 (bibliographic concepts). ISO 4 also interfaces with international transliteration standards for Cyrillic and Greek scripts.
