William Dean Howells,
Some Anomalies of the Short Story…
“ It is not quite so clear as to when and where a piece of fiction ceases to be a novella and becomes a novel. The frontiers are so vague that one is obliged to recognize a middle species, or rather a middle magnitude, which paradoxically, but necessarily enough, we call the novelette. First we have the short story, or novella, then we have the long story, or novel, and between these we have the novelette, which is in name a smaller than the short story, though it is in point of fact two or three times longer than a short story. ”
