FRBR
• “Functional Requirements for Bibliographic Records”
• Pronounced “fur-bur” or “eff are bee are”• Outcome of an IFLA study, approved in 1997
– Study’s aim was to “produce a framework that would provide a clear, precisely stated, and commonly shared understanding of what it is that the bibliographic record aims to provide information about, and what it is that we expect the record to achieve in terms of answering user needs”
• http://www.ifla.org/VII/s13/frbr/frbr.pdf(or Google: frbr +ifla)

• A “conceptual model”• Intended to relate the attributes and
relationships of bibliographic records in respect to the tasks that users perform
• An attempt to recommend a set of minimum data requirements that would provide a basic level of functionality based on user needs
FRBR is…

• A standard• Intended to replace AACR2 • An alternative to MARC21 or any other MARC
format
FRBR is not…

Basic User Tasks
• Find materials using search criteria • Identify an entity as being the desired
object • Select an entity that is appropriate to
their needs • Obtain the entity (or access to it)
![Page 6: Functional Requirements for Bibliographic Records: FRBR and Millennium](https://reader036.vdocuments.us/reader036/viewer/2022062809/5681598d550346895dc6d67f/html5/thumbnails/6.jpg)
FRBR Entities
• Group 1 (WEMI): what is described by the record– Work - distinct intellectual or artistic creation (e.g.,
Shakespeare’s Hamlet)– Expression - intellectual or artistic realization of a work (e.g.,
video recording of a performance or an English language text version of Shakespeare’s Hamlet)
– Manifestation - physical embodiment of an expression of a work (e.g., the video recording of a performance of Shakespeare’s Hamlet released by Columbia Pictures in 1997)
– Item - single exemplar of a manifestation (the physical piece with a barcode attached to it)
• Group 2: who is responsible for the creation, production, etc. of the entity (individuals and corporate bodies)
• Group 3: the subjects of the entity (concept, object, event, and place)
![Page 7: Functional Requirements for Bibliographic Records: FRBR and Millennium](https://reader036.vdocuments.us/reader036/viewer/2022062809/5681598d550346895dc6d67f/html5/thumbnails/7.jpg)
Group 1 Entities
• Nature of the entities– The intellectual or artistic content are reflected in the
work and expression – The physical form is defined in the manifestation and item
• Relationship between entities– A work may be realized through one or more than one
expression – An expression is the realization of one and only one work– An expression may be embodied in one or more than one
manifestation; likewise a manifestation may embody one or more than one expression
– A manifestation, in turn, may be exemplified by one or more than one item

• FRANAR (FRAR?): Functional Requirements and Numbering of Authority Records
• Group 2– Authority records for names (persons, families,
corporate bodies), titles and name-titles
• Group 3– Authority records for subjects (concept, object,
event, place)
Group 2 & 3 Entities
![Page 10: Functional Requirements for Bibliographic Records: FRBR and Millennium](https://reader036.vdocuments.us/reader036/viewer/2022062809/5681598d550346895dc6d67f/html5/thumbnails/10.jpg)
Possible Approaches
• Split bibliographic records into 3 separate records (work record, expression record, manifestation record)– Not defined by MARC standard– Implications for record loading and output– Whole new way of thinking for cataloging staff?
• Add data to existing records to define which the data comprising Group 1 entities (work, expression)– Not defined by MARC standard– Less disruptive to cataloging staff?
![Page 11: Functional Requirements for Bibliographic Records: FRBR and Millennium](https://reader036.vdocuments.us/reader036/viewer/2022062809/5681598d550346895dc6d67f/html5/thumbnails/11.jpg)
Innovative Solution
• Automatically build “keys” that define the group one entities appropriate to a bibliographic record– Web OPAC will provide FRBR access via keys– Millennium will automatically create keys in bib
records
• Using OCLC’s FRBR Work-Set Algorithm as a starting pointhttp://www.oclc.org/research/software/frbr/
• Future development may include a more complex linked records approach

• A key is not built: the balance of the record is considered to be manifestation data
What about the Manifestation?
![Page 15: Functional Requirements for Bibliographic Records: FRBR and Millennium](https://reader036.vdocuments.us/reader036/viewer/2022062809/5681598d550346895dc6d67f/html5/thumbnails/15.jpg)
• A key is not built: the balance of the record is considered to be manifestation data
• The items are still stored as attached records
What about Items?
What about the Manifestation?

Highly “FRBR-izable”
• Popular fiction• Classic literature• Music• Things with a uniform title• Studies show 15-20% of bib records in
library catalogs are FRBR-izable

Web OPAC and Millennium Clients
Provide a logical grouping of bibliographic records that would allow users to target the desired entity more quickly and easily
Search for author “Mozart, Wolfgang” would include a FRBR entry for Zauberflöte in the results

Challenges?
• Cataloging workload and thought process– Currently, the manifestation is cataloged as a whole
• Record Sharing• How to go back and FRBR-ize existing records in
system?– Not all records benefit from FRBR
• FRBR is appropriate for different works in different libraries
• A work may become a good FRBR candidate long after initially cataloged
• Superworks– Works that have been adapted multiple times (e.g.,
Romeo and Juliet)
