12 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

19 Work Expression Manifestation Item is realized through is embodied in is exemplified by FRBR Group 1 Entities

20 FRBR Entity Levels Work: Expression: Manifestation: The Novel Orig. Text Transl. Critical Edition PaperPDFHTML The Movie Orig. Version

21 FRBR Entity Levels Work: Expression: Manifestation: The Novel Orig. Text Transl. Critical Edition The Movie Orig. Version PaperPDFHTML Item: Copy 1 Autographed Copy 2

22 FRBR Entity Levels Work: Expression: Manifestation: The Novel Orig. Text Transl. Critical Edition The Movie Orig. Version PaperPDFHTML Item: Copy 1 Autographed Copy 2 Family of works

23 Attributes of Group 1 Entities Work ID Title Date etc. Expression ID Title Form/mode of expression Date Language etc. Manifestation ID Title Statement of responsibility Edition Imprint (place, publisher, date) Form/extent of carrier Terms of availability Mode of access etc. Item ID Provenance Location etc.

24 Relationships Inherent among the entities Content relationships among works Work Expression Manifestation Item Whole-Part Accompanying

25 25 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 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 FVWG: 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.

36 36 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

37 37 Cataloging an Expression? Working Group Recommendation: Libraries should keep cataloging manifestations (mostly) Expression–level access can be achieved instead through collocation of search results

38 38 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)

39 39 Format Variation Working Group Proposals for AACR Replace ambiguous term uniform title with another term Constructed title? Citation? Add elements to the end of a work heading (uniform title) to identify and differentiate expressions

40 40 Rules for Creating Headings for Expressions in AACR: How? Possible additions to work headings: 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)

41 41 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

42 42 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)

43 43 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

44 44 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

45 45 Preparing for FRBR within AACR (AACR3) Become comfortable with terminology for the Group 1 entities work expression manifestation item Focus on what’s most new and challenging: expression

46 46 FRBR Within AACR: Questions to Consider What is a work?/What is an expression? What’s theoretically rigorous? What will help users? Where might headings for expressions be useful in my library? Is my system vendor thinking about this?

47 47 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

48 48 FRBR and Systems Vendors What can library systems do now to implement FRBR?

49 49 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

50 Collocation by Family of Works and Expressions Shakespeare, William, 1564-1616. Hamlet. + Texts + Motion Pictures + Sound Recordings

51 Collocation by Expressions Shakespeare, William, 1564-1616. Hamlet. + Texts – Danish + Texts – Dutch + Texts – English + Texts – French + Texts – Spanish + Motion Pictures – English + Sound Recordings - English

52 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

53 53 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

54 54 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

55 55 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.

56 56 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?

57 57 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?

58 58 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

59 59 Questions?

60 60 FRBR at the University of Rochester or, Why wait for your System Vendor to implement FRBR?

61 61 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

62 62 Buried Treasure in our MARC Records Relator Information ($e and $4) Shows relationships between Group 1 and Group 2 entities in a predictable place in the record May refer to manifestation being cataloged, or to work or expression represented in it

63 63 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

64 64

65 65

66 66 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

67 67

68 68

69 69 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.)

70 70

71 71

72 72 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

73 73 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

74 74 Is FRBR Really Coming? It’s already here!
