Question

The extra cover that is placed over the hand cover of a book
1. epilogue
2. prologue
3. dust jacket​

Answer 1

Answer:

All physical books are either casebound (hardcover) or paperbound (softcover). Casebound books are sometimes issued with paper covers, which are typically called dust jackets or case wraps. Paperbound books are usually covered in printed heavy weight paper.

Answer 2

Answer:

dust jacket

Dust jackets originally displayed cover information on top of a simple binding, at a time when it was not feasible to print directly on to the binding. The role of a dust jacket has been largely supplanted by modern hardcover printing technologies, which prints such information directly on to the binding.

Modern dust covers still serve to display promotional material and shield the book from damage. The back panel or flaps of the dust cover are printed with biographical information about the author, a summary of the book from the publisher (known as a blurb) or critical praise from celebrities or authorities in the book's subject area. The information on the dust jacket often resembles that of the binding, but may have additional promotions about an edition, and the information on the flaps is not typically copied onto the binding.

The dust jacket protects the book covers from damage. However, since it is itself relatively fragile, and since dust jackets have practical, aesthetic and sometimes financial value, the jacket may in turn be wrapped in another jacket, usually transparent, especially if the book is a library volume.
