Abstract
The lower part of the book can be torn off along a line of perforations if required, so that the key, written in this section is not directly available to the reader. The outer parts of the pages of the lower part of the book can be torn off and used as playing cards. The idea is equally applicable to books of puzzles in which the answers can be separated from the problems.
