Are you interested in expanding your library of picture books by and about American Indians? This recent post, "#IndigenousReads by Indigenous Writers: A Children’s Reading List," from EmbraceRace.org offers suggestions featuring authors and illustrators from tribes across the US and Canada.
You can find more book recommendations, from board books to books appropriate for high school students, on the American Indians in Children's Literature (AICL) website. The site also includes links to book reviews and critical reflections on ways indigenous peoples are portrayed in children's and young adult books, the school curriculum, popular culture, and society.
As you make decisions on what to assign and/or buy for your library, I also encourage you to look at Evaluating American Indian Materials and Resources for the Classroom, published by the Montana Office of Public Instruction.
Some of you may also find this post from last November useful: "Teaching Indian Literature and/or Literature about Indians." (Among other things, it features many of OPI's Model Teaching Units. I just updated the links to reflect their new website design.)
