A combination binder/book rest having front and rear covers (10, 12) pivotally connected along opposed edges of a spine (14). A support element (52) is pivotally connected to the front cover to support the front cover at a selected angle of inclination. A page retention mechanism (86, 88; 98, 100; 106, 108) rotatably connected to the spine bears against pages of a book (110) supported by the inclined front cover. An adjusting mechanism (56, 74, 76) is provided for adjusting the cover's angle of inclination. When not functioning as a book rest, the device may be configured in a storage position in which it functions as a conventional three-ring loose-leaf binder. The binder's contents (27) may be easily removed for reference while the device is functioning as a book rest. The book rest aspect of the device provides improved support by utilizing one of the binder's covers to support the open book. The page retention mechanism may be adjusted to accommodate books of many sizes.
