Abstract: A device for facilitating the reading of a book by holding its pages in an open position, includes an elongate member 100 which terminates in two inwardly-directed end-pieces 101 and 102. The end-pieces are pivotally connected to the elongate member 100 with finger and lever portions 30 and 32 disposed on opposite sides of the pivot. Coil springs 203 are provided to urge the finger portions against the pages of the book, and the fingers have straight margins 36 of curved cross-section. The end-pieces thus maintain a substantially constant pressure on the pages irrespective of the number of pages being held. The elongate member 100 includes telescopically-engaged inner and outer elements 108, 107 allowing the spacing between the end-pieces to be adjusted, and a separate platform element 13 is attached to the outer element to support the cover of the book.
