Legends, traditions and laws, of the Iroquois, or Six Nations, and history of the Tuscarora Indians Book

The legends (with one exception) are Squamish and were told to Johnson by Chief Joe Capilano (also with a few exceptions). Pauline Johnson was clearly a gifted storyteller, and I think a good part of the reason people continue to find the stories so compelling is the way she tells them. However, I think the way the stories came about and are credited brings up some interesting questions/issues with respect to written vs. oral storytelling, as well as the weight we place on the importance of the book. None of the oral storytellers are given co-author credit, and while Joe Capilano is at least mentioned by name, some of the stories are told to Johnson by a woman (or women? it's unclear whether it's the same woman or different ones) who isn't identified.
