Anna Tingley writes: “Two documentaries premiering at Sundance this weekend are set thousands of miles apart—in Nairobi, Kenya and Texas, respectively—but at the heart of their stories is the same thesis: the importance of libraries to any healthy democracy. Kim Snyder’s The Librarians follows a group of librarians who have resisted book bans in Texas, Florida, Iowa and beyond. The urgency of the Sarah Jessica Parker-produced documentary is underscored by another film on the lineup: Maia Lekow and Christopher King’s How to Build a Library, which follows two Kenyan women’s mission to restore a public library in the country’s capital, Nairobi, and transform the formerly whites-only library into a cultural hub that reflects the contemporary, youthful, creative metropolis that exists today.”
