Anne of Green Gables is a bestselling novel by Canadian author Lucy Maud Montgomery published in 1908. It was written as fiction for readers of all ages, but in recent decades has been considered a children's book. Montgomery found her inspiration for the book on an old piece of paper that she had written at a young age, describing a couple that were mistakenly sent an orphan girl instead of a boy, yet decided to keep her. Montgomery also drew upon her own childhood experiences in rural Prince Edward Island. Montgomery used a photograph of Evelyn Nesbit, which she had clipped from New Yorks Metropolitan Magazine, and pasted the framed clipping on the wall of her bedroom, as the model for the face of Anne Shirley, the book's main character.Montgomery also found inspiration in the "formula Ann" orphan stories, the Anns without the e. Other characters, like Gilbert Blythe, were modeled, in part, on real-life characters. Montgomery wrote the novel in the twilight of the day, sitting at her window and overlooking the fields of Cavendish. Since publication, Anne of Green Gables has sold more than 50 million books. In addition, this book is taught to students around the world.
