Fantastic fiction includes fantasy, science fiction, weird fiction, and some pulp fiction like Doc Savage. Related critical and biographical works are also indexed here. I have erred on the side of including borderline cases like contes cruels.

“Raw Feed” links take you to what are essentially my lightly edited notes on the work. They may include spoilers.

“Low Res Scan” links take you to capsule reviews.
