Osmosis: a new way of updating holdings on the New Zealand union catalogue ne2010

  1. 1. OSMOSIS : a new way of updating holdings on the New Zealand union catalogue Ksenija Mincic-Obradovic Cataloguing Manager The University of Auckland Library k.obradovic@auckland.ac.nz ALA conference, OCLC stream 26 June 2010
  2. 2. Before 2007 •NZ NUC was the main cataloguing utility •Original cataloguing on NZ NUC or on local catalogues •New holdings reported to NZ NUC •OCLC WorldCat only a few libraries; for records not on NZ NUC + CJK cataloguing Individual Libraries
  3. 3. Since 2007 daily •NZ NUC source for NZ records; WorldCat source for other records •New holdings reported to either Individual Libraries Over 5,000,000 records Nearly 16,000,000 holdings 280 member libraries
  4. 4. But … • Adding new holdings somewhat patchy • Some older material (including theses, rare material) not reported • Deletions and transfers rarely reported… … and, this causes a series of problems
  5. 5. OSMOSIS Pilot project • OSMOSIS – a software tool that identifies changes (additions and deletions) to library holdings, developed by TMQ (Fla) in 1992 • Project began in 2008 – National Library of New Zealand – University of Auckland (first pilot library) – Auckland University of Technology – University of Canterbury – Victoria University of Wellington – Porirua Public Library – ELGAR – Libraries for a Greater Auckland Region • 2009 – technical improvements to batchloading to the NZ NUC (service offered to pilot libraries only)
  6. 6. Process • Library exports a copy of entire database and sends to TMQ • TMQ Processing: – Pre-processing: Fixes errors and pulls problem records and sends reports to library – OSMOSIS: compares new file with previous file and identifies adds and deletes; and sends files to NLNZ • NLNZ runs TMQ’s PLP/MCU batchload matching algorithm software to identify and resolve duplicates before loading to the NZ NUC

  8. 8. OSMOSIS Checking Options
  9. 9. OSMOSIS Fixing Options, 1
  10. 10. OSMOSIS Fixing Options, 2
  11. 11. MCU Record Comparison
  12. 12. Problems resolved: •Serial holdings/enumeration data •Translation tables– library symbols to NZNUC codes •Material not to be represented on NZ NUC and WorldCat (e.g. purchased records for eebo)
  13. 13. Problems unresolved: •Duplicate records •Inadequate metadata •Initial effort for setting up the services off-putting for some libraries
  14. 14. • Accurate holdings on WorldCat and NZ NUC • More effective resource sharing and interlibrary loan fulfilment • Greater visibility of NZ libraries’ collections • Improved workflows • Various errors in the catalogue were reported, e.g. duplicate records and mistakes in MARC coding Errors fixed by manual interventions or global changes (MARC Global, Gary Strawn’s programmes) Benefits:
  15. 15. OSMOSIS Reports
  16. 16. Good Quality Records Enable: • Resource discovery • Accurate machine matching • Reduction of record duplication on NZ NUC and WorldCat • Projects involving metadata conversions • Database mergers • Improved faceting and FRBRisation on Primo
  17. 17. Future of the OSMOSIS project • OSMOSIS appears to be useful method whereby: – Participating libraries attain maximum NUC/WorldCat reporting (both additions and deletions) – Standardisation of cataloguing practices across libraries is encouraged • Recommendation to extend OSMOSIS service to additional 10-15 libraries in 2010-2011 financial year • TMQ and NLNZ discussing RDA/MARC implications
