Although L.M. Montgomery (1874–1942) is best remembered for the twenty-two book-length works of fiction that she published in her lifetime, from Anne of Green Gables (1908) to Anne of Ingleside (1939), she also contributed some five hundred short stories and serials to a wide range of North American and British periodicals from 1895 to 1940. While most of these stories demonstrate her ability to produce material that would fit the mainstream periodical fiction market as it evolved across almost half a century, many of them also contain early incarnations of characters, storylines, conversations, and settings that she would rework for inclusion in her novels and collections of linked short stories.

In Twice upon a Time, the third volume in The L.M. Montgomery Library, Benjamin Lefebvre collects and discusses over two dozen stories from across Montgomery’s career as a short fiction writer, many of them available in book form for the first time. The volume offers a rare glimpse into Montgomery’s creative process in adapting her periodical work for her books, which continue to fascinate readers all over the world.
