Manuscript Preparation, Copyediting, and Proofreading

Q. The place of publication is included in the front matter of a printed book. Is the place of publication also included in the front matter of an e-book?

A. Yes. Publication has to do with where books are acquired and edited (which applies to e-books), not where they are printed, which is most often somewhere else.
