  • Patent number: 4487156
    Abstract: A bookmark, comprising an anchoring member 1, 2 for securing the bookmark to the cover of a book, and a pointer 3 connected to the anchoring member and adapted in use to overlie an edge portion of pages of the book, and extending generally in the direction of a center portion of the spine of the book, the arrangement being such that the pointer is capable in use of flexing outwardly of the pages of the book on turning of a page, to allow passage of the page past the pointer. The outermost end of arm 4 carries a small stop 6 which is positioned to bear on the top edge of the book cover when used with a hard-backed book. This urges the outer end of arm 4 upwardly, and thus the pointer 3 downwardly, to compensate for the fact that the pages of a hard-backed book are generally lower than the cover.
