One can generally make out if I have read the book in my possession. Between the pages of such books one can find leaves/flowers put in for drying. One can also find money. These articles do not act as book marks. They are just there because the book I was reading happened to be a convenient receptacle for it. My family, of course, laughs at me. Amma, till she was well, would generally go through the books and other unlikely places confiscating the money she found. She made quite a packet out of this.
I thought I was alone in this idiosyncrasy. Till I came across this article where UVA's book traces project tracks human interactions with physical books. Tucked into books were leaves, hair, tracings, and of course annotations. Ah! that makes me feel better.
And maybe this is why I do not quite like e-books. One can't tuck in things!
