New York transit officials have collaborated with Penguin Random House to bring “Subway Reads”—a platform that offers e-literature based on how long riders will be on the subway—to New York subways, the New York Times reports.

The initiative, intended to promote use of New York’s WiFi service at 175 underground stations, will last for eight weeks. Better yet, all Subway Reads ebooks—which include novellas, short stories, or excerpts from full-length books—will be free.

Currently, Subway Reads is offering five novellas or short stories, including “High Heat” by Lee Child, “3 Truths and a Lie” by Lisa Gardner, “At the Reunion Buffet” by Alexander McCall Smith, “The Diamond as Big as the Ritz” by F. Scott Fitzgerald, and “The Murders in the Rue Morgue” by Edgar Allen Poe. There are also dozens of excerpts from fiction and nonfiction books.

Subway Reads will help book industries learn about subway readers. Child, who lives in Manhattan, says he’ll be looking around at his fellow riders, making his own observations.

“You can tell by their finger movements,” he said to the New York Times. “If they’re playing a game on their phone, they’re stamping at it all the time. If it’s a book, you can tell the regular turning of the page.”

WiFi service first arrived to New York’s subway system in 2011, when six subway stations received connectivity. The plan has been to give connectivity to New York’s 278 underground stations by 2018, but Governor Andrew M. Cuomo ordered the project to be accelerated. According to the Times, officials expect to complete the project by the end of 2016.

Meanwhile, in Melbourne, Australia, a group calling itself Books on the Rail is leaving physical copies of books on the public transport for commuters. People can sign up with them to become “book ninjas” and help out the cause by leaving books on their routes.
