FRBR basics: 

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:: 

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: Navigate

FRBR defines 3 groups of entities: 

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

Slide6: 

From William Denton (http://www.frbr.org/) intellectual/ bibliographic units agents 'aboutness'

Group 1 Entities: 

Work Expression Is realized through A distinct intellectual or artistic creation The intellectual or artistic realization of a work The physical embodiment of an expression A single exemplar of a manifestation Group 1 Entities

'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: 

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 andamp; management intelligence New insights into works (e.g., OCLC’s 1000 list) Libraries can operate at workset level (e.g., ILL)

OCLC Research: 

OCLC Research Mission: To expand knowledge that advances OCLC's public purposes of: Furthering access to the world's information Reducing library costs Description: ~ 30 staff (including 8 scientists) in Dublin, OH Applied research in metadata, taxonomies, search standards, retrieval systems, user IR behavior, digitization, collection analysis, and related areas Also various standards work (e.g., Dublin Core)

Audience Level: 

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' OCLC Research Team: Lynn Connaway (lead) Brian Lavoie Ed O’Neill Cliff Snyder Akeisha Heard

Calculating “audience level”: 

Calculating 'audience level' Sum of Holding Weight ÷ Total Holdings 139.63 ÷ 177 = 0.78 Operations research for libraries and information agencies : techniques for the evaluation of management decision alternatives by Donald H Kraft andamp; Bert R Boyce [San Diego : Academic Press, ©1991]
