This brief and gentle introduction  to some key concepts laid out in the IFLA-produced Functional Requirements for Bibliographic Records paper should be read by any librarian wondering what all the "ferber" fuss is about. Scratch that. It should be read by any librarian period. It's time for us to admit our library catalogs are a mess from a user's perspective, and FRBR can provide at least a partial solution to the problems we face in fixing our systems. Therefore, knowledge of the basic concepts that are already beginning to transform our bibliographic systems should be considered basic, foundational, professional knowledge. So start here, if you must, but then feel free to follow up with the full report .
