发明名称 Book leaf holder and marker
摘要 A book holder having slender fingers affixed to the ends of a telescoping frame serves to hold a book open when the frame is positioned across the back of a book's spine while orientation of the frame along the book's spine allows the device to serve as a book marker when the book is closed. The adjustability of the telescoping frame allows a wide range of book widths and spine lengths to be accommodated.
