Today I want to point you to their newsletter for teachers. Five issues are available online. Here's a screenshot of the most recent one (Winter 2015):
in 2009, I wrote about When the Rain Sings: Poems by Young Native Americans that is featured in the newsletter for Winter 2015. In that second paragraph above, Renee Gokey pointed to the selection criteria developed at the American Indian Library Association for its Youth Literature Award, a rubric for evaluating books, and my page of Best Books.
Visit the NMAI site and read the newsletters! In the current one, you'll see two more wonderful books on the first page: Sweetest Kulu and House of Purple Cedar.
The newsletter talks about Never Alone, too, which I haven't looked at, but know is highly regarded by many of my colleagues.
And--there's a note, too, about what is coming in the next newsletter: how to engage children in difficult topics, like Indian Removal.
