Tin House, the Portland-born publishing company, has announced it will stop publishing the literary magazine that was its genesis. The 20th anniversary issue, to be released in June 2019, will be the last, publisher Win McCormack announced today.

McCormack attributed the decision to "the current costs of producing a literary magazine," in an announcement that included a note from the magazine's editor, Rob Spillman. Tin House plans to focus resources on the company's book-publishing arm and its summer workshop at Reed College, which draws about 200 writers every year for an intensive week of workshops and seminars, with a nightly reading series at the school's leafy amphitheater.

Over its two decades, Tin House magazine has published such authors as Deborah Eisenberg, Richard Ford, Seamus Heaney, Miranda July, and Marilynne Robinson, among other writers of fiction, poetry, and essays.

"It has been an honor to work with such smart, dedicated colleagues, and to publish the most exciting, vital voices of our time," wrote Spillman, who was the magazine's co-founding editor, along with his wife, Elissa Schappell.

"To those writers who have submitted to us over the years, thank you for tirelessly tackling the difficult, important work of making art," said McCormack. "It’s been our honor and pleasure to read your writing."
