A document support monitor stand for removably mounting a document holder includes a monitor fitted with a pair of receiving mortises. The mortises are located at the the front side of the monitor, vertically aligned at opposite sides of the display screen, with each having its entry opening disposed in a forward facing direction and having a series of cooperating niches for securing the document holder. A document holder includes a copyholder, a dual ball and socket assembly, and an engageable support arm for mounting and securing the document holder on the document support monitor. The support arm includes an engagement portion having, securing, niche-engageable, springboards, which is slidably received by either one of the receiving mortises by means of the mortise's entry opening so that the document holder may be frictionally secured to the monitor. The stand allows the copyholder to be extended, and retracted, and to also be adjusted laterally, vertically and universally with respect to its rotational position.
