Abstract
Abstract This book holder comprises a spine in form of a container for batteries. The container is open at the top so that the batteries can be dropped down therein. A cover closes the top of the container. Leaves hinged to the upper ends of the side walls of the container, extend outwardly to support the covers of a book placed in the holder, with the spine of the book resting on the cover of the container. A lamp holder is mounted on the forward end of the container and has a hinged lamp adjustable to direct light to various parts of the leaves of the book on the holder. A switch on the container is controlled to automatically turn the lamp ''''on'''' when the holder leaves are spread open to open the book for reading and to turn the lamp ''''off'''' when the leaves of the holder are brought together to close the book. The book cover can be slipped under bands on the holder leaves to open and close the book when the holder is opened or closed, respectively.
