One of my favorite things is book dedications and inscriptions. I love a good dedication--from simple ones like the fact that Vladimir Nabokov dedicated every book he wrote to his wife Vera, to more elegant ones like this CS Lewis one.
I have a very small collection of used books that have inscriptions in them from other people. There are a couple that make my heart do a little flip from their sweetness & simplicity. One of my favorites is a book I ordered for a travel literature course I took a few years ago. It simply said, "From one world traveler to another." I love imagining the scenario behind the inscription. Was it a romantic gift? A gift from one friend to another? Or something written impulsively by the person giving up the book & meant for the next person that found it?
