Hardcover binding is created with paper wrapped around board. The joining of these two elements protect the interior book block. All of PRC’s hardcover books are Smyth Sewn and case bound, processes which provide the best longevity.
Paperback books, on the other hand, are only bound with paper instead of a hard board cover, although the cover material is usually a thicker stock than the interior pages. Paperback interior book blocks are either saddle stitched, glued, or signature sewn and glued to cover stock.
