Last month I shared some thoughts about how indexes seems to be a thing of the past, at least when it comes to ebooks. I’ve given more consideration to the topic and would like to offer a possible vision for the future.
Long ago I learned the value an exceptional indexer can bring to a project. For example, there’s a huge difference between simply capturing all the keywords in a book and producing an index that’s richly filled with synonyms, cross-references and related topics. And while we may never be able to completely duplicate the human element in a computer-generated index I’d like to think value can be added via automated text analysis, algorithms and all the resulting tags.
Perhaps it’s time to think differently about indexes in ebooks. As I mentioned in that earlier article, I’m focused exclusively on non-fiction here. Rather than a static compilation of entries in the book I’m currently reading, I want something that’s more akin to a dynamic Google search.
Let me tap a phrase on my screen and definitely show me the other occurrences of that phrase in this book, but let’s also make sure those results can be sorted by relevance, not just the chronological order from the book. Why do the results have to be limited to the book I’m reading though? Maybe that author or publisher has a few other titles on that topic or closely related topics. Those references and excerpts should be accessible via this pop-up e-index as well. If I own those books I’m able to jump directly to the pages within them; if not, these entries serve as a discovery and marketing vehicle, encouraging me to purchase the other titles.
This approach lends itself to an automated process. Once the logic is established, a high-speed parsing tool would analyze the content and create the initial entries across all books. The tool would be built into the ebook reader application, tracking the phrases that are most commonly searched for and perhaps refining the results over time based on which entries get the most click-thru’s. Sounds a lot like one of the basic attributes of web search results, right?
Note that this could all be done without a traditional index. However, I also see where a human-generated index could serve as an additional input, providing an even richer experience.
How about leveraging the collective wisdom of the community as well? Provide a basic e-index as a foundation but let anyone contribute their own thoughts and additions to it. Don’t force the crowdsourced results on all readers. Rather, let each consumer decide which other members of the community add the most value and filter out all the others.
This gets back to a point I’ve made a number of times before. We’re stuck consuming dumb content on smart devices. As long as we keep looking at ebooks through a print book lens we’ll never fully experience all the potential a digital book has to offer.
