noncasebound

Noncasebound refers to books that are bound without a rigid outer cover, or case. This contrasts with casebound or hardcover books, which have a hard outer shell typically made from boards and fabric or leather. Noncasebound formats rely on flexible covers or no cover at all and encompass a range of binding styles.

Covers for noncasebound books are usually paper or light cardstock and may be fully softcover or involve simple binding methods. Common noncasebound bindings include pamphlet or saddle-stitch binding (stapled or sewn pamphlets), spiral or comb bindings, wire bindings, and perfect binding (glued spines). Text blocks in noncasebound formats can be sewn or glued, but the emphasis is on flexibility rather than a rigid case.

Production and use of noncasebound formats are typically cheaper and faster than casebound editions. They are lighter and easier to mass-produce, making them popular for magazines, catalogs, school textbooks, trade paperback editions, and other formats intended for broad distribution. Durability is generally lower than that of casebound books; spines and covers can wear more quickly with handling and transport.

History and variants: The rise of noncasebound formats accompanied the growth of mass literacy and publishing efficiency, complementing hardcover editions. Today, noncasebound is a broad descriptor used in publishing and library catalogs to identify books that do not employ a rigid, hard-cover case, including softcovers, paperbacks, and various flexible binding styles.
