Alison Marcotte writes: “About a decade ago, filmmaker Dawn Logsdon started documenting life in libraries throughout the country. Since she began filming, public libraries have been on the front lines of a battlefield over intellectual freedom, facing threats of closures and an unprecedented surge of book challenges and bans. In the upcoming documentary Free for All: The Public Library, which premieres April 29 on PBS’s Independent Lens, Logsdon and codirector Lucie Faulknor trace the public library’s history since the late 19th century. American Libraries spoke with the duo about libraries in today’s sociopolitical climate and the unsung heroes in library history.”
