A structured metadata description of a bibliographic item that identifies and characterizes the resource for purposes of discovery, citation, access and management; typically includes creator/author, title, edition or version, publication or issuance information, identifiers (ISBN/ISSN/URI), physical or digital format, subject access points, and provenance or holding information.

Principle

A bibliographic record functions as an interoperable, machine‑readable surrogate that enables resource identification, retrieval and linking across catalogues and services when its elements follow shared rules and controlled terms.

Demonstration

Illustrative scenario: A cataloguer creates a bibliographic record in the institutional catalogue, supplying a standardized title field, an ISBN in the identifier field, an authorized subject heading, and a location/holding note. Because the record uses standard element names and controlled terms, the discovery layer returns the item for keyword and subject searches and an interlibrary‑loan system can match the ISBN to request copies from another library.

Misapplication

Treating the bibliographic record as the same as the resource’s content or as an exhaustive representation. The semantic error is assuming the record contains the work itself or all bibliographic relationships; it is a descriptive and access-oriented representation, not a surrogate for full content or an authoritative edition statement without supporting provenance fields.

Consequence

Well‑constructed bibliographic records increase discoverability, enable automated linking (e.g., to holdings or digital objects) and support resource management; inconsistent or incomplete records fragment search results, cause duplicate entries, and hinder interoperability between systems.

Reversal

When the cataloguing context is archival description, museum cataloguing, or data‑centric repositories, the metadata model and required elements differ; minimal or unqualified records (e.g., a single citation line) may be sufficient for some discovery needs but will not support functions that require structured access points or unique identifiers.

Boundary

Clearly within: a catalogue entry using defined element names and controlled headings that supports lending, discovery and citation. Boundary case: a bibliographic citation in a bibliography that provides identification but lacks structured access points or identifiers. Clearly outside: a full‑text file, an institutional administrative record (e.g., circulation transaction), or raw user comments about a work.

Semantic Tension

Consistency and standardization (necessary for interoperability) versus local descriptive nuance or institutional practices (necessary for local resource management and user needs).

Synthesis

A bibliographic record is an operational instrument: not the object itself but the standardized description that permits reliable identification, discovery and machine processing across systems.
