The book is still a bestseller with more than 30 million copies in print. In 1999, it was voted "Best Novel of the Century" in a poll by the Library Journal.
According to The Writer's Almanac, when the book was first published in 1961, "The opening line of the Washington Post review read, 'A hundred pounds of sermons on tolerance, or an equal measure of invective deploring the lack of it, will weigh far less in the scale of enlightenment than a mere 18 ounces of new fiction bearing the title To Kill a Mockingbird.'"
