FRBR-izing the Library Catalog: a look into the OPAC of the
future
What is FRBR?Functional Requirements for Bibliographic Records
A conceptual information model developed by IFLA
Based on 3 groups of entities and their relationships to each other
Each entity has attributes (title, date, language, name)
Used to fulfill 4 User Tasks (Find, Identify, Select, Obtain)
Group 1 Entities and Relationships
is realized through an…
which is embodied in a…
which is available as an…
Group 1 Entity ExamplesWork (the conceptual intellectual endeavor)
Romeo and JulietExpression (format, language)
Spanish translation, recording of the performance, online text
Manifestation (embodiment of an expression)
1772 text edition of the French translation, 1968 annotated text
Item (a copy of a manifestation held in a library)
Copy of the 2002 Cambridge Press edition held at Hillman Library
Group 2 Entities and Relationships

How does the AACR2-based OPAC already reflect FRBR principles?

Current OPAC (PittCat +)Finding, Identifying, and SelectingExcellent for refining by format, language,
author, subject headingsNot good at tracing bibliographic
history/editionsNot very good at grouping by relationships
Books about the work, adaptationsRelationships between works (books about
the work…)
Good at “obtaining”: holdings information, request feature
Making the most of FRBR: RDA (Resource Description and Access)
A new set of cataloging rules that would replace AACR2
Created according to the FRBR modelRecording attributesRecording relationships (primary relationships,
relationships to, relationships between)
Designed to be more flexible in order to conform to different encoding formats (not just MARC) and therefore work better in online environments
ILS (Integrated Library System) Challenges
Does your current ILS vendor carry products that make the most of FRBR principles in its catalog display?
Some examples:VTLS: Virtua and RDA Sandbox (MARC based)eXtensible Catalog (open source, non-MARC
based)
Do you buy a new ILS or wait until your current ILS offers RDA/FRBR-related products?
What would it take to make the most of FRBR in a library OPAC (Online Public-
Access Catalog)?Display according to FRBR principlesNew cataloging rules: RDAEncoding format: Right now, early
implementations of RDA are encoded in MARC but are other encoding schema (Dublin Core, XC Schema) in the OPAC’s future?Pro: A new encoding format could be better
suited for the semantic web, which is important considering the increase of digital information.
Con: Converting the millions of MARC-based catalog records!
More issues to considerEntities aren’t clearly defined : How will it work with
other kind of information such as archives, museums, art, and film?
Existing FRBR-based protypes are very narrowly focused: a need for more generalized examples of FRBRized catalogs
Few user studies: Do we know if it will it truly make information search easier for library users?
Cost effective (does your institution even have the money)?Time and effort in learning new rules and new formatsConverting to a new system
