Abstract

Abstract A sheet of opaque plastic the shape and dimensions of a book page, with an arrow cutout shaped in the sheet extending beyond the page on the right edge as viewed when a book is opened, to indicate as to whether it is the upper or lower part of either page where the user's reading was interrupted. Also, a self-adhesive movable arrow label positioned on the right or left edge of the opaque plastic sheet to indicate the exact line on either page where reading was interrupted. This enables a reader to locate the exact line where reading was interrupted without looking over approximately eighty lines on two pages by glancing at both arrows. In addition, by viewing only five lines through an elongated rectangular cutout, eye strain is reduced.
