A page indicator tab (1) may be provided by cutting out a tongue-like section in parallel with free side edge (2) of a paper page. The section (1) is provided at a predetermined distance from the side edge (2), thus providing a remaining strip (3) between the section (1) and the side edge (2). The section (1) is folded along an oblique line (5) in relation to the side edge (2) and then pushed through a slit (6) already formed between the section (1) and the strip (3). The section (1) is now held in place by the counteracting forces from a base part (4) of the section (1) and the strip (3).
