RDA entities Based on modern international models Work, Expression, Manifestation, Item, Person, Corporate Body (FRBR) Family (FRAD) Work-Expression-Manifestation-Item are discrete components of a resource. This avoids duplication of data E.g. Work creator and Expression language are linked to, not copied in, multiple Manifestation descriptions such as a printed book and e-book
