An identification insert for inserting into one end of a rolled drawing for identifying said rolled drawing from a stack of similarly rolled drawings and the method thereof is disclosed. The insert is a tubular member with an outwardly extending flange at its rearward end and at least one longitudinal slot extending from adjacent its rearward end and opening at its forward end. The outwardly extending flange provides a surface for identifying indicia such that the drawing can be easily identified when viewed from the end into which the insert is inserted. The identification insert is circumferentially compressible at its forward end such that in one mode of use it exerts a wedging effect against the innermost layers of the roll as its forward end is inserted therein. In another mode, the inner lap of the rolled drawing is caught in said longitudinal slot and the rolled drawing tightened on the insert by holding the inner lap of the drawing such that it will not slip on the insert and twisting the insert in the direction that the drawing is rolled. In a still further mode, the inner lap of the rolled drawing is wedged in said longitudinal slot.
