A book with a flexible cover, often made of heavy paper or thin card, is characterized by its soft, bendable nature. This style of binding allows the book to lie relatively flat when open, enhancing readability. A common example is a trade paperback with a thicker, more durable cover than a standard mass-market paperback.
This binding method offers a balance between durability and affordability. It provides a more robust feel than a standard paperback while remaining less expensive than hardcover alternatives. Historically, this type of binding has served as a practical solution for volumes intended for frequent use, such as textbooks or journals, where the flexibility improves handling and reduces wear and tear compared to rigid covers. This approach continues to be a popular choice for a wide range of publications.
