I focus on paperback books. If there’s a need to created a jacket for a hardbound book, I’m happy to expand. See the page discussing book cover design considerations for the Internet.
These examples are my own books. I have new covers in progress for a publisher and I’ll post those asap.

Front Cover: title, name, and appropriate graphic; and design and placement of blurbs, if any. Thought is given to creating a brand image if there are multiple books by the same author, and especially for nonfiction books
Spine: includes title, author name, and imprint logotype
Back: includes graphic for ISBN number (which can include price); cover blurb (editorial assistance provided); and design and placement of blurbs, if any.
