"The National Book Critics Circle Award for Nonfiction is an annual award presented by the National Book Critics Circle (NBCC) to recognize the best works of nonfiction published in the United States during the preceding year. It is one of six awards presented by the NBCC. The winners are chosen by the NBCC's voting members, who are professional book review editors and book reviewers.
The NBCC aims to 'promote the finest books and reviews published in English' and foster a national conversation about literature, criticism, and reading. Books previously published in English, like re-issues or paperback editions, are not eligible. Translations, short story and essay collections, and self-published books are considered.
The NBCC awards are unique because they are chosen directly by book critics, making them one of the most prestigious literary honors in the United States."
