Functional Requirements for Bibliographic Records (FRBR)

FRBR, or Functional Requirements for Bibliographic Records, is a framework that helps organize and describe library items like books, movies, or music. It clarifies how different versions or formats of the same work relate, such as a novel, its audiobook, and its movie adaptation. FRBR groups these into levels: the original work, the expressions (like translations), the manifestations (specific editions), and items (individual copies). This system improves discoverability by making it easier to find all related versions of a work and understand their connections, enhancing library cataloging and user experience.
