The Internet may be disrupting much of the book industry, but for short-story writers it has been a good thing.

Story collections, an often underappreciated literary cousin of novels, are experiencing a resurgence, driven by a proliferation of digital options that offer not only new creative opportunities but exposure and revenue as well.

Already, 2013 has yielded an unusually rich crop of short-story collections, including George Saunders’s “Tenth of December,” which arrived in January with a media splash normally reserved for Hollywood movies and moved quickly onto the best-seller lists. Tellingly, many of the current and forthcoming collections are not from authors like Mr. Saunders, who have always preferred short stories, but from best-selling novelists like Tom Perrotta, who are returning to the form.

Recent and imminent releases include “Vampires in the Lemon Grove,” by Karen Russell, whose 2011 novel, “Swamplandia,” was a finalist for the Pulitzer Prize; “Damage Control,” a first collection by Amber Dermont, whose novel “The Starboard Sea” was a best seller in 2012; and another first story collection, “We Live in Water,” by Jess Walter, just off his best-selling novel “Beautiful Ruins” (2012).
