A Linking book (D'ni language: Korvahkh) is a book written according to the Art, complementing and facilitating the usage of a Descriptive Book and linking to an Age. Like the Descriptive Books, the Linking Book featured a Linking panel. Linking Books make linking more convenient and portable. A Linking Book is simply written as a reference to a Descriptive Book, with a common combination of paragraphs and descriptions pointing to the original Book; no phrases are needed in the Linking Book from any Descriptive Book.
