Why does continuing the use of traditional knowledge matter?

Quillwork on a traditional birchbark book. The front cover reads "G.W.O. Ypsilanti" in purple-dyed quill. The back cover has a red heart in the center. Both covers feature a green wreath.
Andrew Blackbird (Makadebinesi) (Odawa, American, 1814-1908), Margaret Blackbird Boyd, binding and illustrations (Odawa, American, 1817-1892).

History of the Ottawa and Chippewa Indians of Michigan: A Grammar of their Language/ Personal and Family History, The Ypsilantian Job Printing House, Ypsilanti, Michigan, 1887. Amherst College Archives and Special Collections, Collection of Native American Literature E99.O9 B6 1887 c.2

By embellishing this important book with an expression of a traditional art form, Boyd uses her quillwork skills for a different purpose than most artists did at that time.
