Some ECHO institutions house esthetically and historically important collections, which they share with visitors, with scholars and with other institutions.
Notable collections reside at the Peabody Essex Museum in Salem, Massachusetts, the New Bedford Whaling Museum, also in Massachusetts, and the Bishop Museum in Honolulu.
Smaller but equally important collections reside at the Inupiat Heritage Center in Barrow, Alaska, and the Alaska Native Heritage Center in Anchorage.
The Mississippi Band of Choctaw Indians owns invaluable items of cultural patrimony, which it keeps in trust for its own members.
