Most of the Dolly Parton tributes hitting social media on Tuesday focused on her music career, but the Library of Congress decided to celebrate her 30-year commitment to improving literacy.The country music legend died on Aug. 25 after “a brief battle with cancer” at the age of 80. To honor her memory, the Library of Congress posted a picture of Parton reading to children with this tribute: “The Library is devastated to learn of the passing of @DollyParton, a music legend and titan of children’s literacy. Her Imagination Library program has earned multiple Library Literacy Awards and, in 2018, she visited us to donate its 100 millionth book to our collection and host a story time.”To honor the memory of her late father, who was illiterate, she started Dolly Parton’s Imagination Library in 1995 in Sevier County, Tenn. The program, which donates books once a month to families with young children from birth to age 5, aims to help foster a love of reading in children.During its 31-year history, Dolly Parton’s Imagination Library has donated more than 300 million books and has become one of the world’s largest childhood reading initiatives. Fourteen percent of kids in the U.S. who are under the age of 5 receive a book by mail, according to the foundation’s About Us page.In her 2022 acceptance speech for the Carnegie Medal of Philanthropy, Parton said that while her dad couldn’t read or write, “he was a very smart man, and I often wondered what he could have done had he been able to read and write. So that is the inspiration.”Watch Parton celebrate the donation of her 100th million book at the Library of Congress in 2018 below:
