Copy holders (a.k.a. "copy hinge") attach to the side of your computer's monitor and hold a piece of paper up at eye level. This makes it easy to duplicate or refer to the page when keyboarding, without repeatedly looking down at your desk. Some use a clip, others hold the paper with rollers.

Different types of holders are available for both kinds of computer displays (CRT, LCD), along with desk-mounted units. A holder which attaches to the monitor helps to conserve desk space. Brands include Fellowes, Belkin, and Kensington.
