Just this morning I had the idea that since so many books are appearing in electronic format it won't be long before lots of the text has been tagged. I'm reading an enjoyable book about sleep right now. In many places the author goes into personal stories that led to a particular discovery. I thought 'wouldn't it be nice to be able to have those parts filtered for me by my Kindle software?'. I could see things getting to the point to where you could have the option to generate an executive summary from any popular book that tries to hit the main points. Then you drill down as you want more information. Books could function almost like mini-wikis at that point but with a narrative or order that you use to drive through it.
