Oakland Public Library has unveiled a display of the sweetest items left in their books by people who have returned them.
"Found in a Library Book" has treasures spanning over decades, including unsent love letters, family photos, and postcards.
"There are some that are letters or cards or postcards that were sent between people - or maybe not actually sent - that feel really personal," says Sharon McKellar, a supervising librarian.
"Some notes and letters feel very unfinished. Or I really want to know what happened next."
