Or maybe when you get to that passage, with the swipe of a finger you highlight it and email it to your dad, adding a thanks for his gift. Or you click to add your thoughts to a chorus of readers who found that same passage interesting; or you check to see if there's a link to a video clip; or you find an annotation from the author; or you post it to Twitter or Facebook or Google+, where others can comment on it too.
"Increasingly, the devices we use to read — the Kindle, your iPad, various types of phones and other devices — they're connected," says James Bridle, a British writer and publisher who's been at the forefront of ebook development. "They have a whole bunch of capabilities that the paper book didn't have."
Put those connected, capable devices together with books and add the best aspects of social networking — sharing, conversation — and the result is social reading. It is a logical step that's still taking shape; it's in its Wild West days, mapping out boundaries, players staking out sometimes overlapping territory.
Amazon was an early entrant; people reading on its Kindle have long been able to post favorite passages to Twitter and Facebook. It hasn't gone much further than adding limited annotation. Kobo, Canada's most popular e-reader, has picked up where it left off.
When using Kobo's devices (and its apps for the iPad and Android tablets), users read with Kobo Pulse, a brightly colored, interactive, multifaceted interface. Externally, a single click with Kobo Pulse will tell Facebook or Twitter what you're reading or post a short passage. But the inside of the book is really dynamic: You can see who else is reading what you are, join in the comment string on a page or start one, view statistics about the book and see everyone's comments within it. A vivid green bookmark drops where you left off reading, and statistics about your own reading habits accrue. There are snazzy awards buttons you earn by finishing more pages, using Kobo's dictionary, highlighting and sharing, and doing something unusual like reading through the night. Although the awards are essentially meaningless, they tempt new users into exploring the service fully. So far, it's the most fully developed social reading interface to come from an e-reader.
One of the most ambitious independent social reading applications is Subtext. Built for the iPad and launched less than two months ago, Subtext offers all of the social reading elements with the added bonus of content from authors themselves. "I was very excited about this," says Amy Stewart, author of "Wicked Plants" and "Wicked Bugs," an L.A. Times bestseller. "As an author, I think a lot of us are thinking about iPad editions. We're all asking ourselves, How could the book I'm writing be more than a book?" Marginal icons show where she added links, video, color images and commentary, including a "Spoiler Alert" warning just to see how the function worked (the determined reader has to tap a second time to see the spoiler). Just like on Facebook, Stewart can respond to reader comments, which also are indicated by icons in the margin.
"We find that one of the big opportunities on Subtext is bringing together book clubs," says Matthew Boyd, manager of special marketing initiatives for Penguin Group USA. Subtext launched with two of the publisher's novels, Jean Kwok's "Girl in Translation" and Lev Grossman's "The Magician King." Boyd is thinking about how the popular Penguin Classics line might work in Subtext. "I would love to experiment with a classroom setting," he says. "You can set it so that all your notes can be read by only a certain group of friends — a professor reading with students could post questions and they could read with each other."
One of the liveliest conversations that has emerged on Subtext is within George R.R. Martin's "Game of Thrones," from the bestselling fantasy series recently popularized by HBO. Although Martin isn't there, his editor Anne Groell is, but the book's fans are driving the conversation. Their lively comments and replies are interesting — whereas many people in *Openmargin are still exploring the app, typing simple greetings or nonsense characters, in "Game of Thrones" readers discuss Martin's uses of language and debate literary references.
Although social reading tools are exciting, they're isolated. As with any other kind of social networking, people using it want to go where their friends are, not to an empty forum. To help draw people in, many social reading services are using Facebook as a connector — but they're just getting started. You might find hundreds of others reading the same book in Kobo, or you might find no one.
That's partly because there are other places to look. U.S.-based Copia was an early player, but European companies have recently debuted more sophisticated interfaces. Launched this summer in Spain and available in seven languages (including English), 24Symbols hopes to be an ebook version of the streaming music service Spotify, highlighting what friends are reading. Berlin-based Readmill, available in English, is focused on sharing content from within books. Openmargin, created in the Netherlands, allows for extended note-sharing within the text of participating books — including "Remix," the 2008 book by Harvard professor Lawrence Lessig.
And so far, most of those applications can't share; buy "Game of Thrones" through Subtext and you won't be able to access it on your Nook. "We have this problem every time new technologies come along. At the moment, we've got a bunch of competing systems," Bridle says. Each system has unique design features, flaws and tricks that take some getting used to — once a reader gets acclimated to Readmill, the features of Kobo Plus may seem baffling.
"For a long time, it felt like ebooks were worse than paperback books. I think we're now getting to the point where people are seeing some of the advantages," Bridle says. But looking ahead he worries that the notes we make and share, which "form incredibly important parts of your experience and your memory," may be lost in the ether, or fall under the ownership of the company that made the e-reading device.
The challenges to social reading may present too much of a hurdle for some. Then again, wouldn't it be nice to find someone to talk about what you just read on Page 57 of Walter Isaacson's "Steve Jobs"?
