Noon-12:45 A Book That Shaped Me: Winners will read their essays from a regional summer writing contest that encouraged rising fifth- and sixth-graders to reflect on a book that has had a personal impact on their lives.

12:55-1:40 Letters About Literature: Every year tens of thousands of students from fourth through 12th grades enter a contest, sponsored by the Library of Congress’s Center for the Book, in which they write a letter to an author — living or dead — whose work has influenced their lives. Some of this year’s winners will read their submissions.

1:50-2:35 The National Student Poets Program will honor outstanding high school poets whose work exhibits exceptional creativity, dedication and promise as they begin a year of service as literary ambassadors.

2:45-3:30 John Hessler and Daniel De Simone will discuss “Galileo Galilei: The Starry Messenger,” which they edited. Hessler is curator of the Jay I. Kislak Collection at the Library of Congress and a fellow of the Royal Geographical Society. He teaches the history of cartography and early modern science at Johns Hopkins University. De Simone is curator of the Lessing J. Rosenwald Collection at the Library of Congress. Signing at 4:30.

3:40-4:25 Fred Hiatt and Ti-Anna Wang will talk about the new young-adult novel “Nine Days.” The book, about two teens who set off to rescue one of their fathers after he disappears in Hong Kong, was inspired by Wang, the daughter of a Chinese dissident who was sentenced to life in prison 11 years ago. It was written by Hiatt, The Post’s editorial page editor and a frequent columnist on human rights and foreign affairs. Signing at 4:45 p.m.

4:35-5:20 Literary Lights Readers Theater: The Center for the Book and its reading promotion partner, the National Children’s Book and Literacy Alliance, sponsor this dramatic presentation in the style of a radio play. Those taking part include young people’s authors Katherine Paterson, Jon Scieszka, Grace Lin, Mary Brigid Barrett and Susan Cooper, and literacy advocate Lynda Johnson Robb.
