  2. Libraries Australia Cataloguing • Cataloguing Client • Web Cataloguing • Record Import Service • Non-roman scripts • Database Quality • MARC record supply / E-collections • System Developments • Standards and Data models

  3. Cataloguing Client • Save whole records (not field-by-field) • Improved user configurability using standard window functions (e.g. fonts and screen colours, toolbars) • Choice of command, button, or keyboard shortcut to invoke most functions • Context sensitive help for each MARC21 field • Templates for easy input of coded data (i.e. 006, 007, 008)

  4. Cataloguing Client (2) • Pick list menu driven data creation form for users who aren't familiar with MARC 21 • Range of MARC 21 templates for experienced cataloguers • Supports input/editing of non-roman script (CJKT) data using Windows Input Method Editors (IME's) and keyboard maps • Some updates (e.g. MARC21 changes) can be implemented without redistributing and reinstalling the Client

  5. Web Cataloguing • Add/change/delete holdings • Create simple bibliographic record • Import records from external databases for copy cataloguing: • OCLC/RLG • Singapore NUC • Te Puna • 3 CJK Databases

  6. Record Import Service • Used by 50 libraries which contribute over 1M bibliographic records and 2M holdings per year • Range of formats supported • Most files are processed within 2 days of receipt • Data quality is important

  7. Non-roman scripts • Thai • Cyrillic, Greek, Tamil • Automatic transliteration • Keyword indexing • Supply to NBD via RIS in Unicode • Receive in RES Unicode products

  8. Database Management

  9. Database Quality • Improved matching and merging and continuing refinement • Retrospective de-duplication of NBD records • Important new contributors • Improved coverage of public library holdings • Timely contribution of data is important

  10. Minimum record standard • One name or uniform title heading if applicable • Title proper • Statement of responsibility • Publication details • Imprint • Leader: Type of record, Bibliographic level, Encoding level • 008 codes: Date of publication, Date 1, Country of publication • For non-Roman script data the 245 field (Title) is mandatory • http://www.nla.gov.au/librariesaustralia/network.html#minimum

  11. Duplicate detection • Identify potential duplicates • Title acronym (4:2:2:1) • ANBD numbers • LC numbers • ISBN, ISSN • Local System numbers

  12. Evaluation • Tri-gram analyses • Calculation of similarity values • More accurate matching • Configurable matching • Overall similarity value: • 0.90  duplicate •  0.60 new record • 0.60 – 0.90 possible duplicate (human review)

  13. Merging • If a tag is only in either the database or incoming record it is retained • Where tags occur in both records merging is based on the source of the record, encoding level and the presence of non-roman script.

  14. MARC record supply • Record Export Service (RES) • File pick-up via website or ftp • Unicode or MARC 8 • New Z39.50 products option • Products or MARC 21 format • Unicode or MARC 8 • Products self-service

  15. E-collections • Australian e-collections • Aggregator neutral records • Serials Solutions agreement • Investigate other sources of e-resource data • EAG on E-resource guidelines • Addition of URLs for resources in major digitisation projects (e.g. million book project)

  16. Standards and data models • FRBR based clustering in LA Search • OCLC work set algorithm • xISBN • Persistent identifiers for ANBD records • RDA • FRBR • GMD/SMD – Carrier/Content

  17. System Developments • CBS 3.2 • Automatic transliteration • Single login for web cataloguing • CJK keyword indexing • Import records from external databases • Display of search query on brief results display

  18. System Developments (2) • Updated cataloguing client in 2007 • Pilot contribution of authority data via RIS • Interfaces to enable NBD staff to manage many system functions: • Global changes • Match/merge configuration • Offline de-duplication • Record linking

  19. Under consideration • Implement an URL checking service • Automated transliteration of other scripts (e.g. Japanese, Korean, Thai) • SRU update

  20. Discussion

  21. Lunch • Reconvene at 1.30 in the main theatre.
