WASHINGTON (AP) — Actress Julianne Moore, radio host Garrison Keillor, and TV’s Hoda Kotb and Jim Lehrer are among the more than 100 bestselling authors, illustrators and poets who are joining the National Book Festival this year.

The Library of Congress has expanded the festival to two days for its 11th year. Events will run Saturday and Sunday from 10 a.m. to 5:30 p.m.

Featured authors include Steve Berry, Toni Morrison and Sarah Vowell.

The expanded schedule may ease some long lines for visitors to hear from famous authors. For those who can’t attend in person, the library is offering online features and author podcasts.

The library says more than a million people attended the festival in its first 10 years. President Barack Obama and first lady Michelle Obama are the honorary co-chairs.
