WorldCat knowledge base data updates
OCLC updates the WorldCat knowledge base every month. See which collections and providers were added or enhanced this month.
Collection data is refreshed on a rolling basis. The frequency of the data updates varies by provider and how often they send their data to the knowledge base team. Once the knowledge base team receives the data we aim to load it as soon as possible.
New collections being added to the knowledge base are documented in our monthly data updates below.
