Winthrop-Young, Geoffrey. "Fallacies and Thresholds: Notes on the Early Evolution of Alternate History"
Summary: Discussion on the nature of allohistorical fiction and of its origins, noting works prior to the 1930s and then the particular roles played by Nat Schachner's w88 android, Murray Leinster's "Sidewise in Time", and L. Sprague de Camp's Lest Darkness Falls and The Wheels of If.
Comments: Part of a special issue on "Counterfactual Thinking as a Scientific Method", but only Richard Ned Lebow's "Counterfactuals, History and Fiction" also seems pertinent to this bibliography.
