  1. Differentiating Libraries through Enriched User Searching: FRBR Implementation in Virtua Back to Basics – and Flying Into the Future Cataloging 2007, Reykjavik, Iceland, 1-2 February 2007 John Espley, Director for Design, VTLS Inc.

  2. VTLS and FRBR • Current Virtua Release is Release 48 • First FRBR customer (UCL) was in 2003 with Release 41 • Important Split for Users • Choose to implementFRBR • Choose to ignore FRBR • Have a mixed catalog with FRBR records and non-FRBR records

  3. Virtua and FRBR • MARC based system • Mapping from regular cataloging to FRBR • One record to three linked records • Work, Expression, Manifestation • Initial mapping done independently by LC (Tom Delsey) and by VTLS (John Espley) – there was little difference

  4. Design Considerations in FRBR • Design is a matter of choices; Good design is a matter of good choices • Five key questions • Store FRBR records? • Have a pure or mixed FRBRized catalog? • What tools are needed to support cataloging? • How to display FRBR records? • What features would users like?

  5. Design Considerations in FRBR Store FRBR Records (or FRBRize at display) ? • Records are cataloged once assessed many times; FRBRizing at access was not optimal • Collocation was easier for stored FRBR records • Validations checks for works, expressions and manifestations was cleaner for stored records • Cataloging was simpler and easily understood

  6. Design Considerations in FRBR Have a Pure or Mixed FRBRized Catalog? • Studies at VTLS and OCLC showed that about 18% of catalog records would gain by FRBRizing • Pure catalogs would be easier to display but would require more effort to convert • Mixed catalogs would take less overhead and provide for gradual (over time) implementation • Mixed catalogs would provide for selective FRBRization if necessary

  7. Design Considerations in FRBR What Tools are Needed to Support Cataloging? • FRBRize button – converts any record to FRBR • Automatic linking between W-E-M records • Context sensitive validation for W-E-M records • Copying “whole” FRBR tree from catalog to catalog • Analyze catalog for FRBR candidates • Batch FRBRize the whole catalog (as in LC music) • UnFRBRize records for distribution & error correction

  8. Design Considerations in FRBR How to Display FRBR Records? • FRBR expandable tree structure • Use of Icons • FRBR reverse tree structure • Music collections • Bound with • See examples that follow later

  9. Design Considerations in FRBR What Features Would Users Like? • Record sensitive displays – standard records display different form FRBR display • Collocation • Multilingual access based on FRBR data • Navigation – hence reverse tree • Circulation holds at W-E-M levels

  10. FRBR Examples • VTLS Implementation • First FRBR customer was UCL in 2003 • VTLS continues to create examples to demonstrate the use of FRBR in library catalogs • Links to 12 examples on following slide • The complete PowerPoint presentation can be found at: • http://www.vtls.com/Corporate/FRBR.shtml

  11. FRBR Examples Click Corresponding button for example

  12. FRBR Implementation

  13. FRBR Demonstration • Beethoven Example • Search on Author Beethoven • Select Symphonies no. 6 • View record and notice FRBR hierarchy • Things to pay attention to now • Notice the 001 and 004 tags • Notice the 999 tag

  14. Beethoven Example Search for Beethoven

  15. Beethoven Example Select 6th Symphony. (Could also select 5 Beethoven and then 6th Symphony)

  16. Beethoven Example Result is a FRBR Work record. (Expand tree by clicking on the plus sign)

  17. Beethoven Example Tree is expanded to display FRBR Expressions. The 004 tag is the 001 of the Work.

  18. Beethoven Example Expanding the tree again displays the FRBR Manifestations.

  19. VTLS FRBR Features • Single database can have FRBR and non-FRBR records • System is “aware” of record type and changes displays as needed • Display of FRBR records are in tree structure • Local level fields have values of W, E, and M to indicate type of FRBR record • 001 and 004 used as linking tags

  20. FRBR OPAC

  21. FRBR OPAC • Screen captures of Virtua’s Web OPAC, iPortal, are presented to show user displays of a FRBR catalog.

  22. FRBR OPAC Search by title

  23. FRBR OPAC Select 1st entry in List

  24. FRBR OPAC Result is a short record display. Click on FRBR tree

  25. FRBR OPAC Result is the FRBR tree with brief info from Work and Expressions

  26. FRBR OPAC Expression has been expanded to display brief info from Manifestations

  27. FRBR OPAC Manifestation record with one owning institution

  28. FRBR OPAC Manifestation record with several owning institutions

  29. FRBR Related Works and Super Works

  30. Work to Work Links • “… when the modification of a work involves a significant degree of independent … effort, the result is … a new work.” FRBR, final report

  31. Work to Work Links • Types of different works: • Paraphrases • Rewritings • Adaptations for children • Musical variations on a theme • Abstracts, digests, and summaries • Adaptations from one form to another • Dramatizations (book to movie, play, etc.) • One graphic art medium to another

  32. Super Work • A Super (or Supra) Work is a record that has other works (sub works) related to it • For example, the novel Beau Geste by P. C. Wren is one FRBR Work, and the several movies that have been created from the book are also separate FRBR Works. The Super work is an artificial creation that links all these related works together

  33. Super Work The Work record for the “Super”Work of Beau Geste

  34. Super Work The tree expanded to show the “sub works” of the Super Work The Work record for the novel (a sub work of the Super Work)

  35. Super Work The Work record for the 1939 movie (a sub work of the Super Work)

  36. Super Work The tree expanded to show the Expression and Manifestations of the 1939 movie The Expression record for the 1939 movie

  37. Super Work The 1926 movie also has two other sub works: music and a Program book The Work record for the 1926 movie

  38. Super Work The tree expanded to show the Manifestations of the 1926 movie The Expression record for the 1926 movie

  39. Super Work The tree expanded to show the Expression and Manifestations for the music (a sub work) of the 1926 movie The Manifestation record for the music of the1926 movie

  40. FRBR Circulation Requests

  41. Circulation Requests • With a traditional system when you had multiple editions of a particular title (Work) you had to place individual requests on each edition (Manifestation). • With a FRBR system, you only have to place a request at the Work or Expression level, and ANY item of ANY Manifestation will satisfy the request.

  42. Circulation Requests Search for the title Action and Passion by Percival Christopher Wren

  43. Circulation Requests The Work Record for Action and Passion

  44. Circulation Requests The Expression record with the tree Expanded to show multiple Manifestations. You do not care which Manifestation you read. You just want one.

  45. Circulation Requests The Manifestations in the next few examples show that items exist in different locations. This location is the Main Library.

  46. Circulation Requests This location is the Mann Library

  47. Circulation Requests This copy is in Green Valley

  48. Circulation Requests This Manifestation has two copies: One each in the Main and Law Libraries.

  49. Circulation Requests Instead of placing a Bib level request at each Manifestation, place the request on the Expression.

  50. Circulation Requests The Request “wizard” is invoked by clicking on the “Add” button
