Abstract
An attachable book mirror device enables the reader of a textual document to view the facial expressions of the young adult, child, toddler, or baby who is listening in close proximity to the reader. The listener can also view the mechanical lip movements of the reader to thereby shorten process of learning to read. The attachable book mirror includes a shell for housing the optically human visual spectrum reflective material that is pivotally connected to a base used to attach to the covers of books or any other suitable document. The reflective material can be adjusted in any allowable position, holding its last position due to certain equal but opposite forces that are generated by certain internal components such as a spring contained within the base that helps create a lasting static contact frictional force. An adjustable light may be pivotally attached to the book mirror.
