Cased hard cover binding is the highest quality binding available. The 80# printed sheet is glued on heavy board to make a smooth outside cover. The cover can be printed in color or black and white. The book block is then attached to the inside of the board making a very durable book cover. We currently do not offer dust jackets or cloth covers and we only offer 5.5 x 8.5, 6 x 9 and 8 x 10.5 (not 8.5 x 11) three sizes. Please keep in mind that the case/hardback bound order production time is longer than our standard turnaround time, the minimum order is 50 copies and maximum number of pages is 410.
