Today on Radio Boston we’re hitting the books and dedicating the full hour to our love of libraries.

We speak with Anita Cellucci, a librarian at Westborough High School and the K-12 Library Department head. She's also a lecturer for Plymouth State University in New Hampshire, where she teaches an online course for children’s and young adult literature.

We take your calls and get the latest spring book recommendations from Katherine Nazarro, manager and bookseller at Porter Square Books in Cambridge and in Boston and Caroline Harvey, co-owner of Dogtown Books in Gloucester.

We check in with Adam Zand and Greg Peverill-Conti, co-founders of Library Land, to get the latest update on their quest to visit all 400+ libraries in Massachusetts, and to discuss how the pandemic has changed our relationship with our local libraries.

We talk with former Newton Mayor Setti Warren, now the executive director of the Institute of Politics at the Harvard Kennedy School.
