12 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
13 FRBR: What is it?
14
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
15 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
16
16 Entity-Relationship Model Entities Relationships Attributes relationship Entity 1Entity 2
17
17 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
18
18 FRBR Group 1 Entities Work Expression Manifestation Item Goethe’s “Faust” L. Filmore’s English translation of Faust As published by W. Smith, 1847 The copy owned by my library

Relationships Inherent among the entities Content relationships among works Work Expression Manifestation Item Whole-Part Accompanying
25
25 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?”
26
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
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
28 FRBR and Cataloging
29
29 Group 1 Entities vs. MARC Or, What are we cataloging? CAVEAT: This is vastly oversimplified! WorkAuthority record Expression???? ManifestationBibliographic Record ItemHolding 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
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., 1 st ed., 2 nd ed.) Some editions are different works altogether (but publisher calls them “editions”)
31
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
32 When do we care about Expressions? Bibliographic families: When a work exists in multiple expressions When an expression exists in multiple manifestations Represent a small percentage of all catalog records, but these represent the core of our cultural heritage
33
33 FRBR and Cataloging: Incorporating FRBR into AACR Joint Steering Committee for Revision of AACR (JSC) FRBR terminology: work, expression, manifestation, item. Incorporating the entity expression into AACR: Format Variation Working Group
34
34 Can We Catalog an Expression? Is it feasible to change the basis for a catalog record from a manifestation to an expression?
35
35 Problems with Cataloging Expressions Not the way most libraries operate We start by purchasing, and then cataloging, a manifestation. Not enough info. at the time of cataloging May needlessly complicate the cataloging process Only useful for a subset of library materials
36
36 Cataloging an Expression? Working Group Recommendation: Libraries should keep cataloging manifestations (mostly) Expression–level access can be achieved through collocation of search results
37
37 Expressions: From Cataloging to Collocation Cataloger-created collocation Propose new rules for AACR for constructing headings for expressions System-created collocation Explore what systems can do with expression-level data already in MARC records (e.g. VTLS, OCLC, RLG)
38
38 Rules for Creating Headings for Expressions in AACR: How? Add elements to the end of a work heading (uniform title) to identify and differentiate an expression Possible additions: 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)
39
39 Possible Headings for Expressions Melville, Herman. Moby Dick. Abridged ed. Homer. Iliad. English (Pope) Berlioz, Hector, 1803-1869. Symphonie fantastique. Sound (Solti) …Order of elements, punctuation being discussed
40
40 Rules for Creating Headings for Expressions in AACR: 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
41
41 Specific Uses of Headings 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 headings (related expression headings)
42
42 Problems with Headings for Expressions How to make the rules clear and easy to use? What elements to add? In what order? What punctuation? Predetermined strings are limiting Every possible solution eliminates all of the others Different users have different needs
43
43 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 headings Some system vendors are already working on this
44
44 FRBR and Systems Vendors What can library systems do now to implement FRBR?
45
45 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
46
Collocation by Family of Works and Expressions Shakespeare, William, 1564-1616. Hamlet. + Texts + Motion Pictures + Sound Recordings
47
Collocation by Expressions Shakespeare, William, 1564-1616. Hamlet. + Texts – Danish + Texts – Dutch + Texts – English + Texts – French + Texts – Spanish + Motion Pictures – English + Sound Recordings - English
48
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

49 FRBR-ize MARC records OCLC’s FRBR Work Set algorithm: http://www.oclc.org/research/softwar e/frbrhttp://www.oclc.org/research/softwar e/frbr/ LC’s FRBR display tool: http://www.loc.gov/marc
50
50 System-Based Collocation: Potential for Improvement? Relator Information Identify roles of entries in a predictable place in the record Proposed revision to AACR2 Rule 21.0D to allow expanded use of relator terms Linking Entries Show relationship between records Pat Riva, article in April 2004 Library Resources & Technical Services
51
51 Assigned Headings 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 headings for expressions when necessary.
52
52 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?
53
53 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?
54
54 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
55
55 Questions?
56
56 FRBR at the University of Rochester or, Why wait for your System Vendor to implement FRBR?
57
57 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
58
58 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/in dex.cfm?page=videos http://www.library.rochester.edu/in dex.cfm?page=videos

61 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/in dex.cfm?PAGE=1333 http://www.library.rochester.edu/in dex.cfm?PAGE=1333

64 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.)

67
67 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
68
68 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
69
69 Is FRBR Really Coming? It’s already here!
