Publishers need to expand their ideas about how readers interact with a book. A lot of readers tend to make notes in the margins, highlight text, or dog-ear pages as they're reading. Instead of traditional tools, readers will be using electronic equivalents. But what will the electronic equivalents be?
Adobe's PDF system has long included mark-up features in its Acrobat product line. Acrobat users can embed notes, scribbles, and other visual elements in PDF documents, and share those marked up and edited files with others. Over the last year or two, many of these features have found their way into Mac OS X via Apple's Preview application. For the tablet, Toporek thinks publishers need to take highlights and annotations to the next level. "An ebook doesn't have to be a static thing that just sits on a shelf," Toporek adds. "Imagine a scenario where the highlights and annotations I make to an ebook can be exported and shared with anyone else who has the same ebook/device." He goes on to add, "It would be great if I could overlay your notes on top of my own so I can see what's important to you."
He envisions a social network of connected readers, built around technical titles. "Wikis and wikibooks never panned out [for these kinds of technical texts] because people were looking for information they could share in but often they weren't willing or able to write it all themselves...[Authors take] great care in building content for their books, investing hundreds, or often thousands of hours in building that content." Readers might build on top of that content by annotating and commenting on text, digitally highlighting their favorite portions and creating "reader cuts" of the text.
A tablet could allow a community to build itself around a book, just like communities now build themselves around popular websites. "Reading a book doesn't have to be a solo effort; it can be communal. Think about taking all those highlights and annotations and storing them on a community server, where readers could overlay the text with that feedback, whether its 2 or 20 or 200 other people. You could toggle that information on and off at will. You can build a community around an ebook, and that's something you just can't get with a print book."
If the tablet does emphasize ebooks the way analysts expect it to, we can only hope that Apple helps show publishers The Way in a future version of the iPhone SDK, similar to Amazon's active content Kindle development kit (KDK) announced yesterday. If the tablet succeeds in its arena, the way the iPhone has before, authors and publishers will be able to Publish Different.
