A paperback is a type of book that has a flexible cover made of paper or thin cardboard. Unlike hardcovers, which have stiff covers and are often more expensive, paperbacks are lighter and easier to carry. They are popular among readers because they are usually more affordable and can fit easily into bags or backpacks, making them perfect for reading on the go. Many bestsellers and classic novels are available in paperback format, allowing readers to enjoy their favorite stories without breaking the bank. Authors like J.K. Rowling and George R.R. Martin have their works published in paperback, making it accessible for a wider audience.
