Zealand union catalogue

ALA conference, OCLC stream26 June 2010
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
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 recordsNearly 16,000,000 holdings280 member libraries
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
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)
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

MCU Record Comparison
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)
Problems unresolved:
• Duplicate records• Inadequate metadata• Initial effort for setting up the services off-putting
for some libraries
• 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:
OSMOSIS Reports
Good QualityRecords 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
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
