Navigating Through Voyager: Should FRBR be in our Future?
Jennifer Bowen
University of Rochester
October 2002
Our Dilemma: Usability + Our Vision + Voyager = ??? Usability testing: Students want a passive entry into the catalog
Our Vision: provide entre into the academic discourse of a discipline
Q: Does Voyager keyword relevance searching provide for our Vision?

Why is This Better?
Collocation: materials with the same or related content are grouped together.
Easier navigation through search results
Precise results with simple search queries.
Q: What could help us to achieve this?
FRBR: Functional Requirements for Bibliographic Records
1997 IFLA document http://www.ifla.org/VII/s13/frbr/frbr.htm
Theoretical model for library catalogs
Uses Entity-Relationship modeling
(entities, relationships, attributes)
Relates all aspects of the catalog directly to user needs/tasks.
FRBR User Tasks
Find through searching
Identify “Is this what I was looking for?”
Select Which best suits the user’s needs?
Obtain “How do I get this?”

FRBR and Voyager?
Voyager can now only group search results for Works (not Expressions) and only when the searcher selects either:
Name/Title Heading Search or Title Heading Search
Next steps for improving Voyager: Allow work-level sorting for All search types More options for user to manipulate search
results (both sorting and display)
FRBR and EnCompass?
Some work-level grouping of search results SHOULD be possible.

Why Implement FRBR in Voyager or EnCompass?
