A hardback, hardcover, or hardbound book is one with stiff covers.
Hardback books may be printed on acid-free paper. They are much more durable than paperbacks. Paperbacks are often printed on cheap recycled paper, and have flexible, easily damaged paper covers. Hardback books are only slightly more costly to make, but are often much more expensive to buy.
