What is the purpose of the Best American Fantasy anthology as described in the introduction?

The purpose of the Best American Fantasy anthology is to showcase the diversity and quality of American fantasy fiction. It aims to capture the imaginative and playful essence of fantasy stories, highlighting their unique qualities and transformative power.

The Best American Fantasy anthology seeks to fill a gap by chronicling the diversity and excitement found in the world of fiction, similar to the approach Judith Merril took with her collections. The anthology emphasizes the imaginative and playful nature of fantasy, valuing stories that challenge and surprise the imagination. It does not aim to define 'fantasy' strictly by fantastical events but rather focuses on the sense of fantastical play and creativity present in the stories. The anthology also aims to establish a solid foundation with rotating guest editors to ensure a vibrant and unique collection.
