The Librarians

From its superb opening-credits sequence paying tribute to card catalogs of yore to its sharp selection of vintage clips and intimate reportage, The Librarians is as well-crafted as it is profoundly alarming.

Kudos are due to supervising editor Mark Becker and his team, who never put a splice wrong. That deft level of craft is maintained throughout, while the aching musical bed by contemporary composer Nico Muhly adds just the right tone of plangent despair tinged with hope.

This documentary lays the facts at our feet and gives us a glimpse of the brave people trying to keep books in libraries and keep young minds open.

Incredibly principled and brave, the librarians talk about their vocation and standing up for the young people for whom libraries are a safe space where they can discover their identity in the pages of books. They really are superwomen.

It’s clear that waters need to be calmed or someone will be hurt, but The Librarians also shows that won’t happen unless people stand up and take action. So it’s a call to arms, then. But, be warned: a horror story too.

Filmmaker Kim A. Snyder’s illuminating documentary — premiering at the Sundance Film Festival — offers a rattling look at coordinated efforts to ban books. More importantly, it introduces viewers to the everyday and increasingly vital heroes pushing back: the librarians who sound the alarm to both legislative and grassroots attempts to pull books from school and public libraries.

We feel very much like we are in the thick of it when watching, as if we're in the room as the story develops.
