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.
What could help us to achieve this?
13
FRBR: What is it?
14
FRBR: Functional Requirements for Bibliographic Records
IFLA publication, 1998 Published by K.G. Saur
Also available on the Web Conceptual model
How do users use bibliographic information?
Relates bibliographic data to user tasks
15
But wait, there’s more… FRAR (or FRAD???) FRAR (Functional Requirements for
Authority Records) May be renamed FRAD (Functional
Requirements for Authority Data) Another model, similar to FRBR Review of draft ended October 2005
16
Significance of FRBR Sheds new light on current
practices, standards AACR, MARC, etc.
A clearer way to communicate about how catalogs should function
Based on needs of catalog users
17
Entity-Relationship Model
Entities Relationships Attributes

FRBR Entities Group 1: Work, Expression, Manifestation,
Item Products of intellectual or artistic
endeavor: Group 2: Person, Corporate Body
Those responsible for intellectual or artistic content
Group 3: Concept, Object, Event, Place Serve as subjects of works

FRBR User Tasks Find
Search for a resource Identify
“What is this resource?” Select
“Will this suit my needs?”
Obtain “How do I get it?”
26
What does FRBR mean for catalogs? Collocation: Bring like things
together in the catalog: Expressions of the same work Manifestations of the same
expression Show relationships between records
in the catalog Help users navigate search results
27
Where is FRBR most useful?
Classics of literature vs. scientific studies Examples in the OCLC database
Stephen King• 102 works, 231 manifestations
Shakespeare’s Hamlet• 1 work, 2696 manifestations
Rowling, J.K. (Harry Potter stories)• 28 works, 300 manifestations
28
FRBR and Cataloging
(Part 1 - Overview)
29
Group 1 Entities vs. MARCOr, What are we cataloging?
CAVEAT: This is vastly oversimplified!
Work Authority recordExpression ????Manifestation Bibliographic RecordItem Holding Record
Current bibliographic records may contain attributes of all four entities! See Library of Congress (Tom Delsey) mapping of FRBR and MARC Bibliographic and Holding Formats
30
Expression vs. edition: Same thing? No! Some editions are the same expression,
but different manifestations Reprint editions, simultaneous
publications Some editions are different expressions:
If content has been revised (Rev. ed., 1st ed., 2nd ed.)
Some editions are different works altogether (but publisher calls them “editions”)
31
FRBR and cataloging Works:
We already use uniform titles for collocation
Expressions: Not currently creating headings for
expressions Attributes of expressions now buried
within bibliographic records
32
Incorporating FRBR into AACR: Toward a new cataloging code
RDA: Resource Description and Access
Incorporating FRBR terminology
Structure based on FRBR User Tasks (find, identify)
Collocation of expressions using citations
First release in 2008
33
Expressions: From cataloging to collocation
Cataloger-created collocation Proposed new catalog rules for RDA for
constructing citations for expressions System-created collocation
Explore what systems can do with expression-level data already in MARC records (e.g. VTLS, OCLC, RLG)
34
Alternative: System-based collocation of expressions
System can identify expression-level data already in the records Use this data to collocate (sort)
displays More flexible than assigning citations
Some system vendors are already working on this
35
FRBR and Systems Vendors
What can library systems do now to implement FRBR?
36
Possibilities of system-based FRBR collocation Works
Can do now, if good uniform titles, clean data
Expressions Possible, but needs work! Can collocate by format, language Can improve collocation without
explicitly identifying every expression
Collocation by family of works and expressions
Shakespeare, William, 1564-1616. Hamlet.+ Texts+ Motion Pictures+ Sound Recordings
Collocation of expressions Shakespeare, William, 1564-1616. Hamlet.
+ Texts – Danish+ Texts – Dutch+ Texts – English+ Texts – French+ Texts – Spanish+ Motion Pictures – English+ Sound Recordings - English
Collocation of manifestations Shakespeare, William, 1564-1616. Hamlet.
- Motion pictures – English+ 1964 Director, Bill Collegan+ 1990 Director, Kevin Kline, Kirk Browning+ 1990 Director, Franco Zeffirelli+ 1992 Director, Maria Muat+ 1996 Director, Kenneth Branagh+ 2000 Director, Campbell Scott, Eric Simonson

FRBR-ize MARC records
OCLC’s FRBR Work Set algorithm:
http://www.oclc.org/research/software/frbr/
LC’s FRBR display tool:
http://www.loc.gov/marc
41
System-based collocation: Potential for improvement? Relator Information
Identify roles of entries in a predictable place in the record
Proposed new rules in RDA will expand use of relator info. (currently covered under AACR2 Rule 21.0D)
Linking Entries Show relationship between records Pat Riva, article in April 2004 Library
Resources & Technical Services
42
Assigned access points or System-based collocation?
Both! Libraries will demand more of systems to
show structure of catalog and collocate search results
AND Catalogers will be able to assign citations
for expressions when necessary.
43
FRBR interface questions for your system vendor What does the FRBR user interface
look like? Will users see a FRBR-like structure? How do users navigate search
results? Is vendor doing usability testing on a
FRBR user interface?
44
More questions for your system vendor What record structure do you use:
“FRBR-Like” (e.g. VTLS) or MARC? Can MARC records be extracted? How will FRBR affect cataloging
interface? How are links made and maintained
between records?
45
What if your system vendor isn’t implementing FRBR? Lobby them! Get other institutions
interested! Make a list of problems that FRBR
would help solve Restate old problems in terms of
FRBR Look for other ways to incorporate
FRBR or parts of it at your library
46
FRBR at the University of Rochester
or, Why wait for your System Vendor to implement FRBR?
47
University of Rochester web projects User-centered web design Alternatives to cumbersome online
catalog searches Use data already in our MARC
records to create websites designed to meet specific UR users’ needs
48
Buried treasure in our MARC records Relator information ($e and $4)
Shows relationships in a predictable place in the record
Language Expression-level attribute
Genre terms Work-level attribute
49
Example 1 UR Video/DVD Collection Circulating collection: for research
AND casual viewing “What directors do you have
represented in your collection?” Use relator info., etc. in MARC
records to create browse lists http://www.library.rochester.edu
/index.cfm?page=videos
50
51
52
Example 2 UR Audio Recordings Relator Information
Users choose performers or composers Problematic: $4 cmp not used for
composers so… Absence of $4 = composers Some false drops, more data cleanup.
http://www.library.rochester.edu/index.cfm?PAGE=1333
53
54
55
Other useful FRBR data Browse by primary language
(videos and DVDs) expression-level attribute
Browse by genre work-level attribute videos and DVDs: mostly LC genre list audio CDs: local list (“record store
categories”: Jazz, Classical, etc.)
56
57
58
The Real Truth UR website project designers didn’t
know about FRBR! Project concept based on user needs Demonstrates viability of FRBR
model regarding user tasks/needs
59
FRBR: May already be at your library! Catalogs already contain some elements
of FRBR There’s more to FRBR than entities and
attributes: emphasis on the user User tasks: find, identify, select, obtain What are our users trying to achieve? User-centered design
60
Is FRBR Really Coming?
It’s already here!
61
Questions?
62
FRBR and Cataloging
Part 2: FRBR and RDA
63
Incorporating FRBR into AACR: Toward a new cataloging code
RDA: Resource Description and Access
Incorporating FRBR terminology
Structure based on FRBR User Tasks (find, identify)
Collocation of expressions using citations
Publication in 2008
64
Group 1 entities vs. MARCOr, What are we cataloging?
CAVEAT: This is vastly oversimplified!
Work Authority recordExpression ????Manifestation Bibliographic RecordItem Holding Record
Current bibliographic records may contain attributes of all four entities! See Library of Congress (Tom Delsey) mapping of FRBR and MARC Bibliographic and Holding Formats
65
Can We Catalog an
Expression?
Is it feasible to change the basis for a catalog record from a manifestation to an expression?
66
Working Group: Can we catalog an expression?
Sound archivist: YES! The performance is the expression Link all recordings of that performance
to it Most group members: NO!
Not the way most libraries operate We start by purchasing, and then
cataloging, a manifestation.
67
Problems with cataloging expressions Not enough info. at the time of cataloging
title of the expression? date of the expression?
If only one manifestation of an expression in the catalog, cataloger may not know: if other manifestations exist, and if so… how the first one relates to others
May needlessly complicate the cataloging process
68
Do we always care about expressions? Only when… Bibliographic families:
When a work exists in multiple expressions
When an expression exists in multiple manifestations
A small percentage of all catalog records (OCLC - 20%), but these represent the core of our cultural heritage
69
Cataloging an expression?
Working Group recommendation: Libraries should keep cataloging
manifestations (mostly) Expression–level access can be
achieved instead through collocation of search results
70
Rules for constructing citations for expressions in RDA: How?
Possible additions to work citations (uniform titles): Language Edition statement Mode of expression (e.g. Sound) Date of expression: date of
performance, translation, etc. Name of editor, translator, performer
(show relationship to Group 2 entity)
71
Specific uses of citations for expressions Useful for small, but important, subsets of
library materials Large collections in a specific area Local research interest Many expressions of the same work Many manifestations of the same
expression More specific related-work citations
(related expression citations)
72
Possible citations for expressionsMelville, Herman. Moby Dick. Abridged ed.
Homer. Iliad. English (Pope)
Berlioz, Hector, 1803-1869. Symphonie fantastique. Sound (Solti)
– these are still just proposals!
73
Rules for creating citations for expressions in RDA: Why? Show relationships between records Move toward rules for how a catalog
should function Demonstrates that collocation at the
expression level is an important function of the catalog
Force an online system to collocate expressions if system won’t do it any other way
74
Preparing for FRBR within RDA: Things to think about What is a work? vs What is an
expression? What’s theoretically rigorous? vs
What will help users? Where might collocation of
expressions be useful in my library? How can I stay informed about RDA?
75
