Jillian Forstadt writes: “The board of the Pine-Richland School District in Gibsonia, Pennsylvania voted Monday to advance a set of major revisions to its controversial library policy. The changes, if given final approval, would reverse measures passed last year that expanded the board’s role in library book selection, broadened parental control over which books are part of the district’s collection, and prohibited librarians from acquiring any materials with ‘pervasive vulgarity or profanity’ or ‘explicit sexual content.’” A slate of Democratic candidates won four seats on the board in November, flipping the district’s conservative majority.
