The museum collections also hold hundreds of archival images and documents pertaining to the history of the three support communities. Comprised of both original source and reproductions, the photographic collection includes images from the 1840s through the twenty-first century. Notable images include a restored photo from the late 1800s of Medina Baptist Church at Six Nations of the Grand River; the famous Community Hall at Ohsweken Fairgrounds; and a collection of portrait images of those members of the three support communities whom served in World War One (incomplete but the Centre is still working on getting photos of each soldier).
The archival documents collection includes several historic books translated into Haudenosaunee languages, personal journals from community members (in both English and Mohawk or Cayuga), land deeds, wills, and minutes from community organizations such as the Six Nations Agricultural Society. Some of the documents have been transcribed and are available for research purposes.
