Book with identification strip has strip inserted in cavity between book spine and book cover before first use

摘要

The book (1) has at least one identification strip (8) fixed in the spine region before first use between the spine (2) and the cover (3). One end (9) of the strip projects from the top or bottom of the book for gripping. The cavity in the spine can be that of the book itself, or a jacket can be inserted to form it.
