Abstract

A paperback-hard cover conversion insert and a method for using same. The insert is usable with a hard book cover having two spaced-apart stiff panel portions and a flexible hinge portion therebetween. The insert includes a flexible sheet attachable to the panel portions; a narrow, stiff piece of material with a configuration typical of that of a spine of a book, having a first side which is convex and a second side which is concave; and a compressible resilient material having in cross-section a generally elliptical configuration. The narrow, stiff piece of material has its first side attached to the flexible sheet between said panel portions, and its second side attached to a first convex side of the compressible, resilient material. The second convex side of the compressible resilient material is attachable to the spine of a book to position the book between the panel portions. The flexible sheet further includes a pair of pockets to receive the soft covers of the book, and the compressible resilient material has longitudinal end guides to assist in longitudinal positioning of the book spine with respect to the compressible resilient material. The second side of the compressible resilient material has an adhesive surface with a peel-away cover. The insert is useful in converting a paperback book to a hardback book, and can be used in the original manufacture of hard cover books.
