The Haunted Hour

The Haunted Hour is an anthology of ghost poetry, published in 1920.
From the Preface:
This does not attempt to be an inclusive anthology. The ghostly poetry of the late war alone would have made a book as large as this; and an inclusive scheme would have ended as a six-volume Encyclopedia of Ghostly Verse. I hope that this may be called for some day.
I have not considered as ghost-poems anything but poems which related to the return of spirits to earth.... If a poem would be a ghost-story, in short, I have considered it a ghost-poem, not otherwise.
Margaret Widdemer (1884 - 1978) was a poet, editor, and novelist. She won the Columbia University Prize (later known as the Pulitzer) in 1919 for her poetry collection, The Old Road to Paradise.
