This is the "official biography" that my publishers use:
Terri Windling is a writer, editor, and artist specializing in fantasy literature and mythic arts. She has published over forty books, winning nine World Fantasy Awards, the Mythopoeic Award, the Bram Stoker Award, and placing on the short lists for the Tiptree and Shirley Jackson Awards. She received the S.F.W.A. Solstice Award in 201o for "outstanding contributions to the speculative fiction field as a writer, editor, artist, educator, and mentor." Her work has been translated into French, German, Spanish, Italian, Czech, Russian, Turkish, Korean, and Japanese. She has served on the boards of the Interstitial Arts Foundation and the Mythic Imagination Institute (U.S.), and is currently a member of the advisory board for the Sussex Centre for Folklore, Fairy Tales, and Fantasy at the University of Chichester (U.K.).
As a writer: Windling has published mythic fiction for both adults and young adults, as well as picture books for children. Her essays on myth, folklore, and mythic arts have appeared in magazines, art books and anthologies in the United States and Europe, and she has contributed to reference volumes including The Oxford Companion to Fairy Tales and Panorama illustré de la fantasy & du merveilleux.
As an editor: Formerly a Senior Editor in the New York publishing industry, Windling now creates and edits book series for a variety of U.S. publishing houses, and serves as an editorial consultant for the Tor Books fantasy line. She has published numerous anthologies for adult, young adult, and middle-grade readers -- many of them co-edited with Ellen Datlow and created around myth and fairy tale themes. Winding and Datlow edited the award-winning Year's Best Fantasy & Horror annual volumes (St. Martin's Press) for sixteen years -- publishing the works of A.S. Byatt, Angela Carter, Vikram Chandra, Susanna Clarke, Charles de Lint, Louise Erdrich, Pierrette Fleutiaux, Neil Gaiman, Stephen King, Ursula Le Guin, Gregory Maguire, Gabriel Garcia Marquez, Steven Millhauser, Haruki Murakami, Peter Straub, Jane Yolen, and other writers of magical literature from around the globe. Windling was also the founder and co-editor (with Midori Snyder) of the online Journal of Mythic Arts, which ran for eleven years and won the 2008 World Fantasy Award.
As an artist: Windling's art has appeared in solo and group exhibitions in the United States and Europe, including shows at The Boston Museum of Fine Arts, The Tucson Museum of Contemporary Art, The Words and Pictures Museum, and The Book Arts Gallery. Group exhibitions have included DreamWeavers (a touring show of fantastical art), Fées (a French museum show of fairy tale illustration from the 12th to 21st centuries), Sir Lanval (a French and English show of art inspired by the medieval Lais of Marie de France), and Ancient Spirit, Modern Voice (an international survey of modern mythic art).
Born in the U.S., Windling now lives with her husband, dramatist Howard Gayton, and daughter, Victoria Windling-Gayton, in a small village on Dartmoor in the west of England.
Okay, that's the formal professional biography.
A less formal one is here.
