Receipts from various stores and bus tickets are the items most frequently found inside returned library books serving as temporary bookmarks. However, the strangest item ever encountered was a coin.
        Bookmarks were created to mark a stopping point, identifying the page or line left off without wasting time searching or re-reading. In the early history, they were typically made of leather or paper. During the Middle Ages and the Victorian era, when books were handcrafted and expensive, bookmarks were elaborately made from ribbon, silver, or silk, becoming fashion items and works of art.
        From the 20th century onward, as color printing on paper became cheaper, bookmarks became an excellent medium for product advertising. Even today, as reading electronic books grows in popularity, reading apps still feature a "Bookmark" function to automatically save progress.
        A good bookmark does not depend on price or material. It should not be too thick which could warp the book's spine nor leave glue residue, color bleeds, or rust stains on the page. It should not slip out easily and must clearly indicate the exact reading point.
