Oprah Winfrey will release a collection of her magazine columns

Winfrey's book 'What I Know for Sure' will be a compilation of columns of the same name that she's written for O the Oprah Magazine.

Oprah Winfrey will be releasing a collection of her magazine columns this fall and the book will be titled “What I Know for Sure” – the same name as her popular  column.

Winfrey has written the column for O, the Oprah Magazine the past 14 years.

“The essays offer a rare, powerful, and intimate glimpse into Oprah’s inner life – her thoughts, struggles, and dreams – while providing readers a guide to becoming their best selves," the publisher Flatiron Books (an imprint of Macmillan), which will be releasing the book, said in a statement. "Candid, moving, exhilarating, uplifting, and frequently humorous, the words Oprah shares in 'What I Know For Sure' shimmer with the sort of truth that readers will turn to again and again.”

Winfrey will write an introduction for the book and, according to industry newsletter Shelf Awareness, the essays she wrote for the magazine will have been edited for "What I Know for Sure."

“What I Know for Sure” will be released on Sept. 2.
