diarticle

Diarticle is a term used in digital publishing to denote a unit that comprises two related articles published as a single object. The concept emphasizes the relationship between the two pieces and supports integrated navigation, shared metadata, and cross-linking.

The term blends di- meaning two with article; in practice, a diarticle may be described as a two-part article or paired publication.

A diarticle consists of two discrete articles bound in a single publication record. They may be released together or sequentially, but are connected by topic, authorship, or methodology. Diarticles typically share a common DOI or a compound DOI and include links that let readers move between the components.

Diarticles appear in scholarly journals, magazines, and digital encyclopedias when two related pieces require simultaneous or cross-referenced presentation. They are used for companion studies, methodological reports and results papers, translations, or two-language editions.

Benefits include improved discoverability and a coherent reader experience, with explicit coupling of related content. Challenges involve indexing and cataloging, ensuring stable linking, archiving, and consistent citation practices across platforms.
