Patent ID: 7004106

Claim:
A bookmark device comprising: an elastically stretchable loop section that includes a first longitudinally resilient cord wrappably attachable to a book in gripping engagement with the book such that said first cord extends across an exterior of the book and between front and back covers of the book at a selected location; an elastically stretchable tail section including a second longitudinally resilient cord joined to and extending from said loop section, said tail section for projecting from a first end of the book to which said loop section is attached and being insertible between a selected pair of adjoining pages of the book to mark a corresponding position therein; said first and second cords constituting a one-piece, longitudinally elastic string, said tail section having an unstretched length, as measured from the location at which said tail section and said loop section are joined to a distal end of said tail section, which unstretched length is not greater than the distance between said first end of the book and an opposite second end of the book; and a tab carried proximate said distal end of said tail section for being pulled to stretch said tail section beyond the opposite second end of the book and for being released such that said tail section elastically contracts and pulls said tab to engage the second end of the book and hold said tail section in place in the marked position of the book.
