Dust jackets are additional paper covers that wrap around hardback books. Your client won’t always ask for this, but it never hurts to be prepared.
Dust jackets are larger than the book cover itself, and you’ll have more room for content on the inside left and right flaps. Use this space for book excerpts, testimonials, extended biographies, poems, quotes or anything else you can dream up.
Talk with your client to determine whether they wante a dust jacket, and, if so, what content they want to include.
