On the occasion of the Center for Children’s Books’ 75th anniversary, the Bulletin staff looked back at previously-published reviews, written by themselves and their predecessors, and reviewed the books afresh from a 2021 perspective. Revisited titles include Harry Potter and the Sorceror’s Stone, The Watsons Go to Birmingham—1963, A Wrinkle in Time, The Snowy Day, and The Absolutely True Diary of a Part-Time Indian.
