Let's say you're stuck on the F train, trying to ignore the person coughing on you, a screaming baby, and a someone staring creepily. (No, I'm not describing my morning). Wish you hadn't forgotten a book? Here's an interesting idea from a group of design students: using tech to bring you the first 10 pages of a popular book on your phone, and then telling you the nearest public library where you can go pick up the actual book. Nice way to possibly get more people back in libraries.
