The free-speech organization PEN American Center says it is giving its 2016 PEN/Allen award to author J.K. Rowling. The prize honors "a critically acclaimed author whose work embodies its mission to oppose repression in any form and to champion the best of humanity."

In particular, the award recognizes Rowling's two charitable foundations — Volant, which works to alleviate poverty and social deprivation, especially among women and children, and Lumos, which helps institutionalized children return to family life.

Rowling is a frequent target of censorship. In 2006, the American Library Association named her the most challenged author of the 21st century.

"I'm deeply honored to receive this award and humbled that my work has been recognized as having moral value by an organization I so admire," Rowling told The Associated Press.

"Through her writing, Rowling engenders imagination, empathy, humor, and a love of reading, along the way revealing moral choices that help us better understand ourselves," PEN American President Andrew Solomon said in a statement. "Through their experiences with Rowling both on and off the page, countless children have learned not only the power of speaking their own minds, but the critical importance of hearing others."

Past winners include Salman Rushdie, Toni Morrison and Margaret Atwood. PEN is also honoring Hachette Book Group CEO Michael Pietsch. Pietsch joined with several other publishers last year in an informal pledge to combat censorship of translated books in China. Hachette also published the posthumous manifesto Open Letter: On Blasphemy, Islamophobia, and the True Enemies of Free Expression by Charlie Hebdo editor Stephane Charbonnier, who died in the terrorist attack on the French satirical magazine last year.
