FRBR basics

FRBR = Functional Requirements for Bibliographic Records

Work done under the auspices of IFLA

Uses an entity-attribute approach to provide a conceptual model of the bibliographic universe

Provides a clearly defined, structured framework for relating bibliographic data to user needs


Four User Tasks:

Find entities that match the search criteria

Identify entities (confirm that the user has found

what they were looking for)

Select an entity that matches the user’s criteria

Obtain access to the entity through purchase, loan, or

through electronic remote access

And, maybe a fifth:And, maybe a fifth:

FRBR defines 3 groups of entities

Group 1: products of intellectual or artistic endeavor that are named of described in bibliographic records

work, expression, manifestation, item

Group 2: entities responsible for the intellectual or artistic content, the physical production and dissemination, or the custodianship of such products

person, corporate body

Group 3: entities that serve as the subjects of intellectual or artistic endeavor

concept, object, event, place

“The FRBR model is revolutionary. The (computer) catalogue is not seen as a sequence of bibliographic records and a replica of the traditional card catalogue, but rather as a network of connected data, enabling the user to perform seamlessly all the necessary functions.”

-Dr. Maja Žumer. National and University Library, Ljubljana, Slovenia


Applying FRBR in services

Incorporating the concepts of the FRBR model in systems:

Superior presentation of search results

Esp. in large files – more intuitive clustering

May help streamline library cataloging

Reduces repeated keying of work-related info

Bibliographic & management intelligence

New insights into works (e.g., OCLC’s 1000 list)

Libraries can operate at workset level (e.g., ILL)

Audience Level

An OCLC Research prototype

A two-step process for assigning a relative “audience level”:

Use MARC “Target Audience” if present

If not, calculate the audience based on weighted holdings

Features:

Human- and machine-readable interfaces

Resolves OCLC record number or ISBN to probable “audience level”
