This desktop stand from Aidata is designed primarily as a bookholder but can easily be rotated into a vertical copyholder. Two adjustable page holders expand to accommodate thicknesses up to .75", keeping books open to the desired location. The 10" wide book ledge extends a full 1" from the middle and tapers back from that point. A convenient rotating stand permits an exceptionally wide range of viewing angles in both book and document orientations and the large, anti-slip rubber ball feet ensure stable positioning at all angles. While not designed specifically as a copyholder it does have clips incorporated both top and bottom which lets thinner documents be inserted and held securely.
