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 ).
