Why are we talking about banning books? The Association of Library Service to Children renamed an award, that's all. It's now the Children’s Literature Legacy Award. Wilder isn't harmed by this, nobody's saying you can't read her books. The only impact is that her name won't be in a press release twice a year.
It's not the end of the world, we don't need to exaggerate it. But I think it's a shame that they chose to deal with the (historically accurate) problematic content in her books by just removing her name from the award. Instead, in a press release twice a year, they could encourage adults and children to discuss problematic content in books and gain a more nuanced understanding of the world. Reading is supposed to make you think and learn and grow, that's why it's promoted, especially for children.
And, I do think she's harmed by it. This group is an authority, and some people are going to take this as a recommendation from an authority that they should not read Wilder's books, or let their children read them. For those who are librarians or teachers, that could mean a lot of kids who are not exposed to Wilder's books unless they stumble across them on their own. You know there will be some school administrators who say, "Just pull them from the library, we don't want any complaints from parents." And yeah, it's dumb because people should think for themselves and read the books for themselves and make their own decisions--but you know a certain portion won't. They'll just go with what the authority suggests. And, sometimes these things start to snowball, and it becomes trendy to do the same thing (downgrade an author or book series), and the effect spreads. Do I think Wilder's books are in danger of becoming extinct? No, not at all. But I think it's a worrying sign that a body dedicated to promoting reading and its supposed benefits, especially for children, would rather just sidestep a very relevant and enlightening conversation about a book's contents.
