A Linking Book is simply written as a reference to a Descriptive Book. Although linking to an Age is possible through a Descriptive Book, it is often more convenient to write a Linking Book that refers to the Descriptive Book. The original Descriptive Book can then be protected, to be used for reference or changes at a later date. Multiple Linking Books can be written that all refer to, and perform the same as a single Descriptive Book. In Díni culture the Linking Books were often much smaller than full Descriptive Books, which presumably allowed for greater portability and which preserved paper.

Linking Books are not used to create links to new Ages (see Descriptive Book). Linking Books are written rather easily and quickly using a common combination of paragraphs and descriptions which may refer to the original Descriptive Book. Linking Books link only to the place where the Linking Book was written in a particular Age. Thus, there is a chance that a Linking Book could be rendered useless if the Descriptive Book with which it was associated was changed in a way that significantly changed the place to where the Linking Book linked.

If a Descriptive Book is destroyed, all Linking Books associated with that Age are rendered useless.

Linking Books cannot be used to link directly from one point in an Age to another point in the same Age. Díni manuscripts seem to infer that the act of linking actually requires some kind of dimensional transfer.
