Data problems

Quality

Duplication

Quality - fullness

of 2.5 M records in our databases

1 M short records

Quality – coding

Duplication

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

Where we are now

• Record sharing

• Short record enrichment

• Automated MARC correction

• Authority control

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

Duplicates lists

Short record enrichment

Results

• Of 1M short records

• 200,000 records processed

• 106,175 records updated

• Will enrich half of our short records? 500,000?

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

Automated MARC Correction

Authority Control

• No authority control in libraries@cambridge databases

• Script written to identify unauthorised headings

• Used program to correct headings

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

Where we are

Fewer records

Better records

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

• 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

• 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!
