To make it unnecessary to carry a pasted tag by attaching a few strings of bundled pasted tags to the front lower part of the bottom board of a book marker.

A few strings of bundled pasted tags 2 are attached to the front lower part of the bottom board 1 of a book marker using a material with appropriate resilience such as Kent paper. In this case, the required number of strings of the pasted tags varies according to the width of the pasted tag 2 and the bottom board 1 of the book marker. Besides, it is recommended that the entire thickness of the book marker is 1mm or less, considering its use purpose. The thickness of the bottom board l1 of the book marker and the number of the pasted tags should be adjusted so that the whole book marker is not excessively thick. Thus it is possible to make it unnecessary to carry the pasted tags 2 as these tags are integrally combined with the book marker.
