Abstract: A copy viewer having a support stand for holding material to be copied in a viewing position and a "see-through" display device for displaying copied material directly over the material to be copied.

Abstract: A copy holder adapted to foster the efficient comparison of two sets of data, one of which is visible on a display associated with a computer, and the other being visible on a sheet of flexible material, e.g., a sheet of paper. The comparison is fostered by reducing the necessary eye travel as an operator switches his attention back and forth between the data on the flexible sheet and the data on the display. A structural housing having a thin profile supports the display device in front of a computer operator, such that an operator may still see the data that appears on the display screen. The housing has a frontal opening through which the sheet of flexible material may be manipulated by the operator; and it has a rear opening through which a surplus quantity of the flexible sheet may be pushed.
