WorldCat Collection Analysis Quarterly Update Complete
OCLC has completed the quarterly refresh of data in WorldCat Collection Analysis, replacing the data from last quarter with the most current data from WorldCat. With this refresh come the following changes:
- Government Documents — All items in OCLC's Government Documents division have been broken out by publishing agency for more granular analysis.
- NLM records consolidated — All master records in WorldCat with a National Library of Medicine call number have been classified using the record's NLM call number. This will be especially valuable for institutions accustomed to classifying their respective collections with NLM. Now the sequence of choosing a call number from the master record to use in mapping an item is:
- NLM
- LC
- Dewey
Coming Soon
In August, look for FRBR-applied WorldCat Comparison for group subscribers. Group subscribers will have the option of applying elements of the FRBR algorithm to their WorldCat Comparison via the FirstSearch Administrative Module. OCLC will announce this new functionality when it is available.
