Abstract: A bookmark which automatically holds a reader's place in a book, which may serve also as a decorative paper clip. The bookmark is made of two flat plates, on which an elastic band is mounted. When used as an automatic bookmark, the plates are mounted on a corner of the book's last page, and the elastic band is stretched to rest diagonally over a corner of any given page of the book. The elastic band serves both to mark the page being presently read, and to press the two plates firmly against each other, tightly clenching the corner of the book's last page. When used as a paper clip, several pages are clamped between the two plates. The plates may be made of plastic sheet. They may be cut from discarded credit card, or incorporated into the plastic carrier framing SIM card.
