Fort Worth ISD’s libraries were closed this week so district officials could inventory their collections and screen for potentially inappropriate reading materials.

Students will not be able to access their school libraries until August 25, reported NBC 5 News.

The screening comes after three titles were removed from shelves for containing sexually explicit content. Copies of the graphic novels Gender Queer: A Memoir by Maia Kobabe, Flamer by Mike Curato, and Wait What? A Comic Book Guide to Relationships, Bodies, and Growing Up by Heather Corinna were all pulled last month, according to the Fort Worth Star-Telegram.

District officials also appear to be getting ahead of an upcoming law that will come into effect in September. The law prohibits school libraries from making “sexually explicit material” available to students.

Such books, many of which feature LGBTQ themes, were at the center of a heated board meeting on July 25, during which several concerned parents and community members questioned why allegedly pornographic material had been made available to students.

As previously reported by The Dallas Express, an activist group called Tarrant County Citizens Defending Freedom (TCCDF) allegedly found 76 different books in circulation at Fort Worth ISD containing “objectionable content.”

Fort Worth ISD’s executive director of humanities and student academic support initiatives, Mary Jane Bowman, told Fox 4 KDFW that the district had mistakenly depended too much on publishers to disclose what kinds of content were in each book.

“Typically, what should be happening is that the director of library media services is also part of reviewing books as they’re coming in. Was that not happening this past year with these several books that were uncovered? That I am not sure. We’re still in the initial stages in terms of who the approved vendors are that we’ll be utilizing,” Bowman said.

Fort Worth ISD informed NBC 5 that Victor Chapa is no longer director of library services.

“Our current interim director is working with our librarians to be able to make sure that we’ve done our due diligence,” Bowman told Fox 4.

Fort Worth ISD fields instructional review requests from the public on its website.

Similar controversies have popped up in several North Texas school districts over the last couple of years.

As previously reported by The Dallas Express, Dallas ISD saw several protests by concerned parents and community members after keeping copies of the book Jack of Hearts (and other parts) by Lev A.C. Rosen on its library shelves for months after some of the sexually explicit content in the title was brought to the board of trustees’ attention.

“If it had been a movie, it would be rated X. It’s offensive and completely inappropriate for our children,” Tami Brown Rodriguez told The Dallas Express back in February.

Dallas ISD pulled the title from library shelves earlier this year. However, the school system still has several controversial titles, including some flagged by TCCDF.
