The board voted Thursday to pull more than a dozen titles from library shelves, despite receiving a report that the district’s libraries aren’t meeting state standards when it comes to the number of books available.

Under the proposed change for the Tennessee school district, librarians would be required to develop a “Mature Materials List” identifying materials within the library collection that have mature content. 

School board members voted to remove “Assassination Classroom” volumes 1 through 8 and 11by Yusei Matsui, “Catch 22” by Joseph Heller, “Perfect Chemistry” by Simone Elkeles, “Water for Elephants” by Sarah Gruen, and “Yolk” by Mary H.K. Choi from school libraries.
