Arts Council England and The National Archives have signed a new collaboration agreement for the three-year period up to 2027.
The bodies said the agreement outlines how they will build on their previous work together to ensure a comprehensive cultural offer for the public.
As partners, the organisations said they "aim to act strategically and practically to help communities across England engage with culture and ensure that our sectors’ collections and activities are accessible to everyone".
Darren Henley, Chief Executive at ACE, said: “The Arts Council has many values in common with The National Archives and we have shared sector audiences particularly in museums and libraries which are fully embedded in our Let’s Create strategy.
"We have already produced joint initiatives such as the Standard Charge and will continue to explore how we can support the sector strategically and practically through the challenges it faces. "
Jeff James, Chief Executive and Keeper at The National Archives, said: "Through this agreement, we will be able to tackle shared challenges across our sectors and make the most of opportunities to advocate, share knowledge and secure funding for arts and culture.”
