In 2014, the library is celebrating 20 years of honoring Salant through journalism-related lectures. The lecture program and the library's Richard Salant Room are named for the late president of CBS news, whose tenure in the 1960s and 1970s included the news challenges of the Vietnam War and Watergate. Salant lived in New Canaan for 37 years. He died in 1993.
