Funding data is available for records entered into Web of Science (WoS) Core Collection since August 2008. Besides the funding data captured from the records themselves, Web of Science Core Collection contains funding information from various other institutions (such us UKRI (UK Research & Innovation), Bill and Melinda Gates Foundation, European Research Council (ERC)).
You can search the Funding Agency and Grant Number field from the Funding Acknowledgment table which displays the funding agency, the grant number, and descriptive funding text. Since May 2021, WoS has enriched this information with funding details captured directly from online grant repositories hosted by funding agencies.
You can also refine search results while you are searching for a Topic. In the results page, select "Funding Agencies" from the "Refine results" preferences on the left hand side.
As another alternative, while you are doing a Topic search, first select "Analyze results" from the menu above the results.
Then, from the Analysis page, select "Funding Agencies" from the drop down menu.
