The invention relates to an overlay for selectively blocking out or covering unwanted information or data on a page having a predetermined layout, such as a television program listing or guide, a class schedule, or a public transportation schedule. The overlay comprises a substantially transparent sheet alignable on the page with indicia and data blocking areas corresponding to indicia and bodies of data of the predetermined layout. The overlay may be partitioned by lines to predefine the data blocking areas. Strips of precut adhesively backed paper or other material sized to fit over selected data blocking areas are attachable on the sheet as desired by a user to cover or block out unwanted information, such as programming unwanted or unreceivable by the user.
