Early-1971, in an effort to attract as many youngsters to the premises as possible, Marguerite Hart — children's librarian at the newly-opened public library in Troy, Michigan — wrote to a number of notable people with a request: to reply with a congratulatory letter, addressed to the children of Troy, in which the benefits of visiting such a library were explained in some form. It's heartening to know that an impressive 97 people did exactly that, and below are just four of those replies, all from authors: Isaac Asimov; Hardie Gramatky; Theodore Geisel; and E. B. White.
(Although sadly a common situation these days, it's worth noting that Troy Public Library is currently dodging closure. How long it remains open is a mystery.)
