Category:Works missing citation information

Most books have a template which displays a cover image and other information, including one section labeled "Cite" and the intention is this links to the publication information for the book: author, year, copyright, publisher, etc. The book template looks for the existence of a "Talk" page associated with the book to determine if the citation information has been added. See for example this book and note how clicking "Publication information" takes you to the "Talk" page.
