"[2] Uncanny has been published bimonthly, beginning in November 2014, after receiving initial funding through Kickstarter.

[6][2] The magazine publishes original works by authors such as Neil Gaiman, Elizabeth Bear, Paul Cornell, Catherynne M. Valente, Charlie Jane Anders, Seanan McGuire, Mary Robinette Kowal, Javier Grillo-Marxuach, Alex Bledsoe, Nalo Hopkinson, Jane Yolen, Naomi Novik, N. K. Jemisin, G. Willow Wilson, Carmen Maria Machado, Amal El-Mohtar, Ursula Vernon, Kameron Hurley and Ken Liu, and published early stories by Alyssa Wong and Brooke Bolander.

[7][2] Each issue includes new short stories, one reprint, new poems, non-fiction essays, and a pair of interviews.

[9] This was a continuation of the Destroy series originally from Lightspeed magazine; in it, the authors and illustrators envisioned "a truly accessible future is one that features rather than erases the disabled mind and body".

[10][11] In 2017, Uncanny won the 2016 Hugo Award for Best Semiprozine, and one of its published stories, "Folding Beijing" by Hao Jingfang translated by Ken Liu, won the Hugo Award for Best Novelette.
