  • ​Work:
    • ​At the highest level of abstraction, a Work in the BIBFRAME framework encapsulates the fundamental essence of the cataloged resource.
    • This includes details about authors, languages, and the overarching subject matter of the resource.
  • Instance:
    • A Work can manifest in one or more individual, material embodiments, known as Instances.
    • These Instances represent specific published forms of the Work.
    • Information associated with an Instance includes details such as the publisher, place and date of publication, and the format of the resource.
  • Item:
    • An Item refers to an actual copy, whether physical or electronic, of a specific Instance.
    • It provides information about the item's location, whether physical or virtual, as well as details like shelfmark and barcode.
