Thank you for your interest in donating artifacts, documents, or images to the Society’s collection.

Potential acquisitions will be assessed by the Collections Committee to ensure that donated materials support our Mission and can find a home here. All donors will be notified of the committee’s decision. Please do not send or bring your materials to the Treaty Site at this time. We will contact you after the Committee has reviewed the donation.
