Value-added in the Convenience of the Printed Page
I can see this kind of truly personalized publishing being expanded and creating a vast new range of one-off titles. Imagine being able to go to a couple dozen websites, say of national parks, and select the information you want to have with you when traveling or researching a given topic. Then that info could be saved, stored, compiled and formatted into a custom book. OK, there are rights issues to work out, and probably payment for content used, but that's mostly logistics. While hardly a killer app, this could be a great link between the web and print, and is another way these two media can be very complementary.
