Abstract
Abstract An index tab is disclosed which attaches over a corner of a sheet or several sheets of paper. The tab includes a tubular body which has a paper enclosing portion receptive to a triangular corner portion of the sheets of paper and a projecting portion which projects from an edge of the sheets of paper. The index tab is attached to the papers by means of a single staple which penetrates both the paper enclosing portion of the body and the corner of the sheets of paper so that the same staple which holds the paper together, also attaches the index tab thereto.
