Catalogue
Synonyms: Online library, Literature database, Reference source, Data provider
Meaning
A catalogue is an online bibliographic data source that allows searching, retrieving, and importing metadata for scholarly works such as journal articles, conference papers, and books. In JabRef, a catalogue refers to an external service or repository — for example, ACM Digital Library, IEEE Xplore, Google Scholar, CrossRef, or arXiv — from which bibliographic entries can be fetched.
Catalogues provide structured metadata (author, title, DOI, year, etc.) that JabRef imports to enrich or create local entries in a user’s library.
Delimitation (Scope and Exclusions)
- Not the same as a library: A library is the local
.bibfile managed in JabRef; a catalogue is an external source from which data is imported. - Not the same as a bibliography: A bibliography is a conceptual collection of works; a catalogue is a retrieval system that provides access to such works.
- Not the same as references: References are selected works cited in a publication, possibly originating from multiple catalogues.
- Not a search engine in general: Although some catalogues expose web search interfaces, their primary function is structured metadata access.
Validity
A catalogue is valid as long as its public interface (API or HTML interface) is operational and accessible.
Different catalogues may use:
- standard interfaces (e.g., DOI, OAI-PMH, OpenSearch),
- custom APIs (e.g., CrossRef REST API),
- or web-scraping-based access (e.g., Google Scholar).
Naming and Uniqueness
Each catalogue is identified by:
- its provider name (e.g., “ACM Digital Library”), and
- its base URL or API endpoint.
In JabRef’s internal configuration, catalogues correspond to fetchers, each implementing a standardized interface for metadata retrieval.
Open Issues / Uncertainties
- Availability and licensing of catalogue APIs may change without notice.
- Metadata quality and completeness vary by provider.
- Rate limits or CAPTCHA systems can restrict automated access.
- The term “catalogue” is JabRef-specific; other reference managers use “online database” or “data source.”
