The $30 entry fee can be paid online via credit card or PayPal.This year's judges are Hugh Sheehy, Karin Lin-Greenberg, Anjanette Delgado, Kristen Nichols, and Sandra Muñoz.Selection process: Each of the four contest judges reads approximately one-fourth of the manuscripts submitted to the competition, with a fifth judge available if needed based on the total number of submissions. Judges select seven to ten finalists each; the pool of finalist manuscripts is read by series editor Nancy Zafris, who makes the final selection of two winning manuscripts and a runner-up. Authors of winning manuscripts receive a cash award of $1,000, and their collections are subsequently published by the University of Georgia Press under a standard book contract. Winners have ten days to accept the award and ten days to sign the contract once it is received. Eligibility: The competition is open to writers in English, whether published or unpublished. Previous winners of this award are not eligible to win again. Writers must be residents of North America.Manuscript Guidelines Manuscripts should be 40,000-75,000 words in length. The award recognizes outstanding collections of short fiction. Collections may include long stories or novellas (est. length of a novella is 50-150 pages). However, novels or single novellas will not be considered. Please be sure manuscript pages are numbered. Please include a table of contents. Please use a standard, easy-to-read font such as Times New Roman in twelve-point size. Stories included in the submission may have appeared previously in magazines or anthologies but may not have been previously published in a book-length collection of the author’s own work. Authors may submit more than one manuscript to the competition for consideration as long as no material is duplicated between submissions. Each submission will require a separate entry fee. Manuscripts under consideration for this competition may be submitted elsewhere at the same time. Please withdraw your manuscript if it is accepted by another publisher and should no longer be considered for the Flannery O’Connor Short Fiction Award competition. Withdrawal can be completed via the submissions manager website. Entry fees are not refundable.

The first page of the manuscript should include the title of the collection only. Please do not include a list of acknowledgments crediting where stories have been published. Judges who recognize work will recuse themselves, and the submission will be reassigned to a different judge.
