Reading between the pages of a book

Emma Smreker has a very unusual hobby. She collects used books, but she rarely reads them. Instead, she hopes to uncover forgotten treasures nestled between the tattered pages. The 30-year-old school teacher from Oklahoma City, Oklahoma, most often finds plane tickets, receipts and dried flowers.

But sometimes she unearths misplaced gems -- photos that tell a story, a poignant poem or a letter that  never got sent. She says, "I have a fascination with old things because it feels like you're holding a time capsule." She revels in these rare finds, and makes it her mission to seek out the original owners and return each keepsake.
