In addition to a high school student and preschooler in the 2,600-student district, the plaintiffs include a chapter of the NAACP and the Authors Guild, a professional organization for writers.The removed books include titles like The Hate U Give by Angie Thomas; The Bluest Eye by Toni Morrison; The Kite Runner by Khaled Hosseini; and Its Your World If You Dont Like It, Change It by Mikki Halpin.The lawsuit is the latest volley in an ongoing battle in the Elbert County community over issues ranging from book bans to LGBTQ rights to allegations that schools are teaching critical race theory. Even some self-described conservative residents have expressed surprise at the school boards recent actions.Last spring, the district decided to switch from its longtime book fair provider, Scholastic, to Sky Tree Books Fairs, which is affiliated with the Christian publishing company Brave Books. The new book fair vendor promised there would be no LGBTQ, critical race theory, dark magic, foul language, or explicit content.The 19 books at the center of the lawsuit are primarily by or about LGBTQ people, people of color, or both. They include discussions of same sex relationships, LGBTQ characters, racism, police violence, or other content Elizabeth school board members considered disgusting, according to the lawsuit.We're on a need-to-know basis.Every weekday morning, Chalkbeat Colorado is bringing thousands of subscribers the news on public schools and education policy that they need to start their day.

It intends to vigorously defend itself and decisions made in the best interest of our children.Last August, the 19 books were temporarily suspended and put on display for a month so parents could review them and make suggestions about their fate.In September, the board ultimately decided to remove the books permanently. But one of the books, Speak by Laurie Anderson, had been checked out of the Elizabeth High School library the previous year and was never returned.Parents had wildly variable opinions about the 19 books at issue, according to the lawsuit.One parent wrote that the book 13 Reasons Why by Jay Asher was just porn. Yet another wrote that it was a prime example of a book that could be a conversation starter + open lines of communication between parents + their children. The book is about a high school student who dies by suicide and leaves casette tapes behind that describe the reasons for her despair.Parents and plaintiffs who opposed removing the books permanently from the library said they want students to have access to books they can relate to and that offer a variety of perspectives.By banning these books, the District is sending the message that it is not okay to learn about LGBTQ+ identities and same sex relationships or race and racism, the lawsuit states.Dozens of other school library books werent removed but ended up on a sensitive list compiled by a curriculum review committee. Parents can prohibit their children from checking out books on the list, which include titles like To Kill a Mockingbird, The Hunger Games and Muslim Festivals Throughout the Year, according to the lawsuit.Note: This story was updated with a statement from the Elizabeth School District superintendent.Ann Schimke is a senior reporter at Chalkbeat, covering early childhood issues and early literacy.
