BIBFRAME (Bibliographic Framework) is a data model for bibliographic description. BIBFRAME was designed to replace the MARC standards, and to use linked data principles to make bibliographic data more useful both within and outside the library community.
The MARC Standards, which BIBFRAME seeks to replace, were developed by Henriette Avram at the US Library of Congress during the 1960s. By 1971, MARC formats had become the national standard for dissemination of bibliographic data in the United States, and the international standard by 1973.
In a provocatively titled 2002 article, library technologist Roy Tennant argued that "MARC Must Die", noting that the standard was old; used only within the library community; and designed to be a display, rather than a storage or retrieval format. A 2008 report from the Library of Congress wrote that MARC is "based on forty-year old techniques for data management and is out of step with programming styles of today."
In 2012, the Library of Congress announced that it had contracted with Zepheira, a data management company, to develop a linked data alternative to MARC. Later that year, the library announced a new model called MARC Resources (MARCR). That November, the library released a more complete draft of the model, renamed BIBFRAME. [nb 1]
BIBFRAME is expressed in RDF and based on three categories of abstraction (work, instance, item), with three additional classes (agent, subject, event) that relate to the core categories. While the work entity in BIBFRAME may be "considered as the union of the disjoint work and expression entities" in IFLA's Functional Requirements for Bibliographic Records (FRBR) entity relationship model, BIBFRAME's instance entity is analogous to the FRBR manifestation entity. This represents an apparent break with FRBR and the FRBR-based Resource Description and Access (RDA) cataloging code. However, the original BIBFRAME model argues that the new model "can reflect the FRBR relationships in terms of a graph rather than as hierarchical relationships, after applying a reductionist technique." Since both FRBR and BIBFRAME have been expressed in RDF, interoperability between the two models is technically possible.
The BIBFRAME model includes a serial entity for journals, magazines, and other periodicals. Several issues have prevented the model from being used for serials cataloging. BIBFRAME lacks several serials-related data fields available in MARC.
A 2014 report was optimistic about BIBFRAME's suitability for describing audio and video resources, but also expressed concern about the high-level Work entity, which is unsuitable for modeling certain audio resources.
- The National Library of Sweden was the first national library to fully transition to BIBFRAME in 2018. 
- Colorado College's Tutt Library has created several experimental apps using BIBFRAME.
- 14 other research libraries are testing the model.
- Ex Libris published a roadmap to implement BIBFRAME in its library systems, which includes a MARC-to-BIBFRAME transformation.
