paperbound
Paperbound is a term used to describe books whose covers and binding are made primarily from paper, rather than hardboard or cloth. In common usage, paperbound is closely associated with the paperback format and is often used interchangeably with softcover, though some contexts distinguish it as emphasizing the binding method (glued spines) rather than the cover material alone. Paperbound editions are typically lighter, less durable, and less expensive to produce and ship than hardcover editions, contributing to wider distribution.
Historically, paperbound editions emerged as a way to offer affordable reading material to a broad audience.
Production and design characteristics of paperbound books typically include a flexible paper cover, a glue-based spine
