White cover of a booklet or book has a problem of getting dirtied easily when placed in contact with tables or desks. In order to overcome this problem the book is given a pair of legs by folding up its corners and the inner pages are trimmed off to follow the fold line. The result is a book that is also a book stand, folding up the corners and spreading the book slightly apart makes it stand. The stability of the stand is achieve with aligning the center of gravity and the mix of different paper thickness.
