In early 1971, Hart wrote to dozens of actors, authors, artists, musicians, playwrights, librarians, and politicians of the day. She asked them to write a letter to the children of Troy about the importance of libraries, and their memories of reading and of books.
Hart received 97 letters addressed to Troy’s young people from individuals who spanned the arts, sciences, and politics across the
50 states, Canada, the United Kingdom, India, the Mariana Islands, and American Samoa.
Those writing included First Lady Pat Nixon; Michigan Governor William Milliken; then-Governor of California Ronald Reagan; Michigan State University President Clifton Wharton, Jr., the first African-American president of a major U.S. university; first-man-on-the-moon Neil Armstrong; Cosmopolitan editor Helen Gurley Brown; authors Isaac Asimov, Hardie Gramatky, Dr. Seuss, Dr. Ben Spock, and E.B. White; and actors Douglas Fairbanks, Jr., Vincent Price, and Dan Rowan and Dick Martin.
