Abstract: An index sheet or divider which may be accommodated by and directly printed upon by a conventional machine printer. The index sheet includes a main body portion and a foldable index tab portion. The index tab portion is transformable into a configuration allowing the index sheet to controlledly pass through a printer. After printing, the index tab portion is transformable into another configuration allowing it to stand out, identify, separate, or otherwise distinguish documents or items with which one or more index sheets are kept. When completed, the index tab portion has back-to-back printable surfaces.
