What “bookcover观察员” means
WikipediaA book cover is any protective covering used to bind together the pages of a book. Beyond the familiar distinction between hardcovers and paperbacks, there are further alternatives and additions, such as dust jackets, ring-binding, and older forms such as the nineteenth-century "paper-boards" and the traditional types of hand-binding. The term bookcover is also commonly used for a book cover image in library management software. This article is concerned with modern mechanically produced covers.
