A document support stand for removably mounting and locking a document holder on the stand includes a main body which may be formed in the shape of a rectangular solid. The body includes a viewing side having an elongated bracket defining a T-slot mounted on it or formed in its surface. Additionally, the stand includes an aperture formed in its body to cooperate with a lock carried by the document holder. The document holder includes an elongated member configured as a T-shaped rail which is slidably received by the bracket of the stand so that the document holder may be mounted on the stand. The document holder further includes a plunger lock which has the dual function of locking the holder to the stand and, at the same time, of locking the rings of the mounted loose-leaf binder in a closed position.
