5. our metadata

6. Is it Newton? NO

7. Is it Voyager? NO

8. Databases! UL and Dependents Departments and Faculties A-E Departments and Faculties F-M Departments and Faculties O-Z Colleges A-N Colleges O-Z Affiliated Institutions Manuscripts

12. Where we were 8 databases University Library: 4 M Other libraries: 2.5 M

13. Data problems Quality Duplication

14. Quality - fullness of 2.5 M records in our databases 1 M short records

15. Quality – coding

16. Duplication

17. Effects Difficulty in resource discovery Patchy retrieval Lack of authority control Difficulty with standard deduplication Burden on staff time Ties us to multiple database model

18. Where we are now Record sharing Short record enrichment Automated MARC correction Authority control

19. Record sharing Departments and Faculties A-E and O-Z moved to a record sharing model Drawing up of guidelines for Cataloguing Automated tools to change the ownership of 825,000 records Legacy duplication of records

20. Duplicates lists

21. Short record enrichment

22. Results Of 1M short records 200,000 records processed 106,175 records updated Will enrich half of our short records? 500,000?

23. Automated MARC correction Corrects MARC coding errors where it can do so without ambiguity In testing, 70,000 records processed in 2 days Over 200,000 errors corrected

27. Authority Control No authority control in libraries@cambridge databases Script written to identify unauthorised headings Used program to correct headings

28. Results DepFacOZ – 2,243 name and subject headings changed, affecting 41,944 records DepFacAE – 620 subject headings corrected, affecting 6,841 records Authority check incorporated into Bib Check program

29. Where we are Fewer of these:

30. More of these:

31. Fewer records Better records

32. Where are we going? One fully deduplicated database of full, well coded records? Catalogue will always be a work in progress Improvements to Catalogue important not only to solve current problems but also to support future developments

33. Data exists independently of Voyager Future developments will rely on quality of data to work effectively –Pushing data out to i.e. discovery layers (Primo, Acquabrowser), platforms (WorldCat, Talis Platform) –Linking to data from outside i.e. RSS feeds, reading lists –FRBR

34. Mixture of automated solutions and traditional cataloguing Catalogue and the records it is made up of are useful tools for the discovery, location and use of our resources We will be ‘Cataloguing’ for a long time to come!
