Wasn’t aware of this:
It happened in 2000. The Harry Potter books — a once in a lifetime publishing phenomenon — were dominating the bestseller lists, with three titles ensconced in the Top 15 at the same time. It just wasn’t fair, moaned publishers of more “serious” fiction. It kept more deserving titles off the list, titles that people would never hear about, said bookstore owners. And so in a rash, indefensible decision, the New York Times decided to banish children’s books solely to their own separate list.
