In the past, publishers and authors had no way of knowing what happens when a reader sits down with a book, but with e-book readers they do:
It takes the average reader just seven hours to read the final book in Suzanne Collins’s “Hunger Games” trilogy on the Kobo e-reader—about 57 pages an hour. Nearly 18,000 Kindle readers have highlighted the same line from the second book in the series: “Because sometimes things happen to people and they’re not equipped to deal with them.” And on Barnes & Noble’s Nook, the first thing that most readers do upon finishing the first “Hunger Games” book is to download the next one.
Some of the findings confirm what retailers already know by glancing at the best-seller lists. For example, Nook users who buy the first book in a popular series like “Fifty Shades of Grey” or “Divergent,” a young-adult series by Veronica Roth, tend to tear through all the books in the series, almost as if they were reading a single novel.
Barnes & Noble has determined, through analyzing Nook data, that nonfiction books tend to be read in fits and starts, while novels are generally read straight through, and that nonfiction books, particularly long ones, tend to get dropped earlier. Science-fiction, romance and crime-fiction fans often read more books more quickly than readers of literary fiction do, and finish most of the books they start. Readers of literary fiction quit books more often and tend skip around between books.
Those insights are already shaping the types of books that Barnes & Noble sells on its Nook. Mr. Hilt says that when the data showed that Nook readers routinely quit long works of nonfiction, the company began looking for ways to engage readers in nonfiction and long-form journalism. They decided to launch “Nook Snaps,” short works on topics ranging from weight loss and religion to the Occupy Wall Street movement.
Pinpointing the moment when readers get bored could also help publishers create splashier digital editions by adding a video, a Web link or other multimedia features, Mr. Hilt says. Publishers might be able to determine when interest in a fiction series is flagging if readers who bought and finished the first two books quickly suddenly slow down or quit reading later books in the series.
