singlework

Singlework is a term used in library science and bibliographic metadata to describe a work that exists as a single, self-contained intellectual creation. It denotes items that are not collections or omnibus volumes composed of multiple distinct works. In practice, a singlework is typically associated with a single primary creator and a standalone form, even though it may be published in multiple formats.

In cataloging practice, works are organized within a framework that distinguishes a work from its expressions, manifestations, and items. A singlework is usually represented in records as one work with a single primary expression, though policy may vary on how translations or format changes are treated. If a work is translated, revised, or adapted, those versions might be recorded as separate expressions or as separate works depending on the cataloging standards in use. The key idea is that a singlework stands as one cohesive intellectual unit, rather than a container for multiple distinct components.

Examples of singleworks include standalone novels, biography manuscripts, or monographs that present a single subject or narrative without embedded contributions from multiple unrelated authors. By contrast, an anthology, a collected works volume, or an omnibus is typically not treated as a singlework because it aggregates multiple distinct writings.

The concept helps inform cataloging and discovery, enabling users to recognize items that represent one complete creation versus those that function as compilations. It is used in conjunction with standards such as FRBR, RDA, MARC, and BIBFRAME to structure relationships among works, expressions, manifestations, and items.
