LANCASTER, Pa. — Samantha Hull was on vacation when she got the call about the missing books.
Eight titles had melted away seemingly overnight, a panicked school aide told Hull, from the shelves of an elementary school in one of the 22 districts Hull oversees as co-chair of a group representing school librarians in Pennsylvania’s Lancaster and Lebanon counties. The books included titles such as “In My Mosque,” which instructs children about Islam; “A Place Inside of Me,” which explores a Black student’s reckoning with a police shooting; and “When Aidan Became a Brother,” whose main character is a transgender boy.
