• The first app to "help" libraries and schools with book bans: BookmarkED, which soft-launched this spring, says it will help parents control what their children read while also helping educators keep up with what's being challenged (BookRiot).

• On when and whether to update text for modern sensibilities: Author Diego Jourdan Pereira has actually been involved in such controversies, so he shares his perspective on the controversy (Writer's Digest).

• Georgia school district cancels an author talk over the word "gay": Author Marc Tyler Nobleman referenced a Batman co-creator's gay son at an elementary school and refused to remove it from upcoming presentations, so the remaining appearances were pulled (New York Times).
