Nearly two decades ago when the Google Books Project digitized and freely distributed more than 25 million works, book publishers argued that free digital distribution weakens the market for physical books. However, new research from Imke Reimers and Abhishek Nagaraj reveals that the opposite — increased demand for physical books, through online discovery — could be true.

The two researchers focused on a particular part of Google Books’ digitized works: those from Harvard University’s Widener Library, which helped seed the project in its early days. The condition that enabled their experiment: Harvard’s digitization effort only included out-of-copyright works, published before 1923 , which were made available to consumers in their entirety. The works from 1923 and later were still copyrighted and not digitized.

The researchers analyzed a total of 37,743 books scanned (扫描) between 2005 and2009. They looked at sales for the two years before this digitization period and the two years after , and found clear differences in the increased sales between digitized and non-digitized books. Approximately 40% of digitized titles saw a sales increase from 2003-2004 to 2010-2011, compared to less than 20% of titles that were not digitized. The increase in sales was also found to be stronger for less popular books.

“If a book is readily available online, people may decide that it’s a useful book and want to buy it,” Reimers said. “The ‘discovery effect’, which even increased the sales of a digitized author’s non-digitized works, is a strong driver of increased sales. It’s not a huge jump in sales , but it’s still good news for publishers.”

“And book lovers,” Reimers said, “are known for their preference for physical books, as opposed to digital versions, which could also play a role.” She added ,“Whenever I talk to people about my research on books, at some point they all say,’ I just love the feel of a digitized author’s non-digitized works, is a strong driver of increased sales. It’s not a huge jump in sales , but it’s still good news for publishers.”

My earliest reading memory takes me back to being five years old, sitting in my grandfather’s cozy study. He would read to me from his French-translated copy of Rudyard Kipling’s The Jungle Book. I was so familiar with the stories that I could correct him word-for-word if he tried to change something.

Growing up, my favorite book was Ray Bradbury’s Something Wicked This Way Comes. It was a treasure for an imaginative and lonely child like me. The book was filled with magical elements: a magical carousel, monsters, and the charming scent of autumn leaves lying in the sun. The language was as crisp and sweet as an October apple, awakening in me a deep passion for words and the magic they could bring out. I’ve reread it regularly and it never fails to satisfy me.

In my adult years, I revisited Emily Brontë’s Wuthering Heights. When I first read it at 16, I perceived it as a love story. However, rereading it as an adult, I was struck by how different it seemed to me, and how much of the humour I’d missed. Now I love its poetry. And the love story not only exists between the characters but between Brontë and the North York Moors.

James Joyce’s Ulysses was a book I came back to after 40 years. Initially, at 15, I found it ugly, depressing, and dull, and I hated it. It took me four decades to return to it, and this time, I found myself understanding and beginning to appreciate it. I could see the details, the mythic parallels, the references to different writing styles, and the groundbreaking technique.

Though some exceptional books can develop and grow alongside us, others fall by the wayside. I’ve revisited so many childhood favourites only to find the magic gone, but I’m usually happy to leave the book behind. I’ve taken from it what I need.

Some people say that we are reading less than ever. In a sense, that’s true, at least for certain forms of writing. However, you might be reading a lot more than you think.

Although printed publications (出版物) still enjoy large sales, you can read many of the same materials online. Some books, magazines and journals can be found online. Blogs and other information resources (资源) can also be easily found. There are lots of materials to read on computer screens.

Reading habits are generally measured by the number of minutes spent in reading. You can also measure these habits by the number of pages. You might think that new television channels and online games, along with the Web surfing, might make people read less. The Internet does influence reading, but the results may be a bit of a surprise.

The Internet has influenced people’s reading habits. However, the time spent in reading books for pleasure doesn’t change a lot, although people are managing to read fewer books every year. In addition, many magazines and newspapers can be read online at any time. Many publications that are weekly or monthly in print form are updated (更新) much more quickly on the Web.

There’s no doubt that online reading has changed what we read and how long we read, and now we read most things less carefully. However, when you consider how much we read, we are still doing a lot. The biggest change is that the medium that we use to read has changed.
