Representative John Lewis won the National Book Award for Book Three in this series. I recommend reading all of them. This graphic novel series follows Lewis through his childhood on an Alabama farm and his struggle to become educated (even by defying his own family) to his civil rights work during the 1950s & 60s with the Student Nonviolent Coordinating Committee (SNCC) to the historic march with Martin Luther King, Jr., and hundreds of other protesters, from Montgomery, Alabama to Selma, Alabama in March of 1965. Later that year President Johnson would sign the Voting Rights Act ensuring access to the vote for African Americans from whom it had been denied.
Books 1 & 3 of the series make specific mention of libraries. Book One gives us the story of Lewis' childhood. He tells how he "loved going the library. It was the first time I ever saw Black magazines like Jet, Ebony, The Baltimore Afro-American, or the Chicago Defender". He gives shout out to librarian Careen Harvey who told her young charges "My Dear Children, Read. Read Everything."
Book 3 tells us that when the Civil Rights Act of 1964 was signed that, among other things, "it ended segregation in public schools, libraries, and parks".
The poignancy of these two points in the story is magnified when one listens to Lewis' acceptance of the National Book Award.
