Abstract: The holder includes a back plate with tabs thereon for capturing the front and back covers of an open book. Hingedly mounted on an upper region of the back plate are a pair of page holders which are spring-biased into contact with the exposed left and right hand pages, respectively, of the open book. The page holders are made of transparent material and have smooth surfaces in contact with the book pages so that the latter are easily slid beneath the holders. The right hand edge of the page contacting surface of the left hand holder is beveled to permit a page to be easily slid beneath that holder as it is turned.
