*These data sources are only available to be searched in Dimensions Plus or Dimensions Analytics.
**Not available in all subscriptions.
These are the frequencies at which the Dimensions team checks for updates to data, or new data, and integrates it. However, it may not mean that new data will be available from all monitored sources. For example, some funders may only release new funding data 2-3 times a year or less, meaning that their funding data will only also be updated in the Dimensions system at the same frequency.
