Here are some of his notable works:
* "The Little Book of Modern Verse" (1915): This anthology was a significant contribution to the popularization of modern poetry, featuring works by many notable poets of the time.
* "A Little Book of Georgian Verse" (1918): A similar anthology, focusing on British poetry of the Georgian era.
* "The Best Poems of 1920" (1921): The first in a series of annual anthologies that he edited.
* "The Poet's Craft" (1938): A volume of essays and poems by Marsh, reflecting his thoughts on poetry and the art of writing.
He also wrote several books of his own poems, including:
* "The Passing of the Idle Days" (1918)
* "The Heights and the Deep" (1936)
However, it's worth noting that Edward Sprague Marsh was also a real person who lived in the late 19th and early 20th centuries. He was a lawyer and a politician, not a writer. It's possible there's some confusion between the two individuals.
