The Center for Native American and Indigenous Research at the American Philosophical Society utilizes the Open to Collaborate Notice. CNAIR strives to work with community-based scholars, knowledge keepers, teachers, and tribal organizations to benefit Indigenous communities and scholarship.
Here you can see a screenshot from the CNAIR website showing the Notice. Unlike TK and BC Labels, Notices are not customized. The Open to Collaborate Notice here reads:
“Open to Collaborate: CNAIR is committed to the development of new modes of collaboration, engagement, and partnership with Indigenous peoples for the care and stewardship of past and future heritage collections.”
