Episode 52, “Libraries and Sustainability”—which originally aired in July 2020—looks at how librarians were living green at the library and in their own lives before the COVID-19 pandemic began. First, American Libraries Associate Editor Sallyann Price speaks with Gabrielle Griffis, assistant youth services librarian at Brewster (Mass.) Ladies Library, about the Blue Marble Librarians, a group that helped promote Climate Prep Week across the state in 2019. Then, ALA Editions Acquisitions Editor Jamie Santoro speaks with René Tanner, associate liaison librarian for the humanities division at Arizona State University (ASU), and Susan Norton, program manager at ASU’s University Sustainability Practices, about the sustainability programs they implemented at their school. Finally, American Libraries Editorial and Advertising Associate Carrie Smith speaks with three library workers from Queens (N.Y.) Public Library who biked from New York City to the 2020 ALA Midwinter Meeting in Philadelphia to raise awareness for sustainability.
