Virtual Union Catalog
Challenges
• ILS Systems - constantly moving target
• Varying Z39.50 implementations
– vendor implementation
– local implementation
– local indexing practices
• Varying cataloging practices
• Varying levels of technology knowledge at
libraries
Colorado Virtual Library
Challenges
• Data inconsistencies
– web resource records without authors
– digitized material records without titles
• Legacy data does not meet
standards
• Local system Z39.50 server
inconsistencies
– e.g. one vendor - title keyword only
