Libraries have been talking about it for 160 years.
Anthony Panizzi, the Principal Librarian of the British Museum, expressed the idea:
“A reader may know the work he requires; but he cannot be expected to know all the peculiarities of the editions of that work. This information he has a right to expect from his catalogues."
IFLA formed a group to study the “functional requirements for bibliographic records” (FRBR), which was eventually consolidated with several other IFLA models to form the Library Reference Model (LRM).
FRBR has been put into practice at 100+ BiblioCommons libraries across the United States, Canada, Australia and New Zealand.
