How frequently is knowledge base collection data updated?

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. You can find the most recent Knowledge Base Data Updates on the WorldCat knowledge base data updates page.
