ABSTRACT:
A book mark that locates an exact line, column, and page in an open book having two or one column pages. The bookmark body is encircled with a slide with an index line that can be moved vertically to align with any line of the text. Two sets of indicia are on the body. One set indicates the desired page, the other set indicates the desired column. In use, the body is first oriented so that the indicia indicating the desired page and column are at the upper portion of the right hand page. And then the slide is moved to indicate the line on that desired column and page.
