Abstract: A readily adjustable and portable book rest includes a support member having a transversely extending fold line providing an upper support member portion above the fold line and a lower support member portion below the fold line. A rigid spine is secured to the upper support member portion and projects therefrom below the fold line, and a flexible adjustment strap extending from the lower support member portion is securable to the spine at different positions therealong to enable the book rest to be erected for use with the upper support member portion at a desired angle. The lower support member portion is angulated about the fold line rearwardly relative to the upper support member portion and the adjustment strap is appropriately secured to the spine to cause the desired angle to be maintained by the book rest when set down on a supporting surface with a lower edge of the lower support member portion and a lower end of the spine being supported thereby.
