The Library of Congress is growing its flagship annual book festival with a yearlong series of literary events that will be called National Book Festival Presents.

This year’s inaugural series will kick off with an appearance from television darling Neil Patrick Harris. On September 11, the celebrated actor, author and magician will present his book The Magic Misfits, the first title in his new series for middle school children.

Other big names in the series will include U.S. poet laureate Joy Harjo, Haitian-American writer Edwidge Danticat, and New York Times bestselling author Malcolm Gladwell.

“With the incredible success of the National Book Festival, we aim to engage even more readers of every age all year long with timely programs that celebrate storytelling, books and creativity,” Librarian of Congress Carla Hayden said in a press release. “National Book Festival Presents will feature a wide variety of subjects for diverse audiences and will highlight groundbreaking works in the humanities and science to fuel our ideas and imaginations.”

The goal of the series is to highlight authors with newly published works in a conversational format, according to organizers. And for the superfans, many of the events will be followed by book signings. In addition, the Library of Congress will showcase parts of its collection that explore themes relevant to the featured books. For now, organizers are hoping to produce two or three events each month.

The new series will be entirely free, but you’ll need to register online, and it’s probably wise to show up early for the most popular events. People can sign up to get event updates via email or check the Library of Congress website for more info.

The popular daylong National Book Festival, launched in 2001, will continue each summer; this year’s is set for August 31. One of this year’s most anticipated authors is Supreme Court Justice Ruth Bader Ginsburg, who will discuss her 2016 book of essays In My Own Words on the festival’s mainstage.

In past years, the event has brought on stars of the literary world from the likes of Salman Rushdie, Neil Patrick Gaiman, and R.L. Stein.

Here’s the lineup for the inaugural National Book Festival Presents series so far.
