Paperback explained to kids

Paperback books are popular because they are usually less expensive than hardcover books and they are more portable. Paperbacks are made of paper that is glued to the spine of the book. The pages in a paperback are usually cut on a fold that is not as deep as the fold in a hardcover book. Paperbacks were first introduced in the early 1800s. They were originally intended to be a cheaper alternative to hardcover books. Paperbacks became popular in the mid-1900s. By the 1960s, paperbacks were outselling hardcover books. Today, paperbacks are still popular. They are often chosen over hardcover books because they are less expensive and more portable.
