520			_aPaper is the basic material used for written communication and the dissemination of information. In addition, paper and paperboard provide materials for hundreds of other uses such as wrapping, packaging, toweling, insulating, and photography. Paper has been defined as a matted or felted sheet formed on a wire screen from water suspension. The word paper is derived from the name of the reedy plant papyrus, which grows abundantly along the Nile River in Egypt. In ancient times, the fibrous layers within the stem of this plant were removed, placed side by side, and crossed at right angels with another set of layers similarly arranged. The sheet so formed was dampened and pressed upon drying, the glue-like sap of the plant, acting as an adhesive, cemented the layers together. Complete depriving, an indispensable element in modern paper making, did not occur in the preparation of papyrus sheets. Papyrus was the most widely used writing material in ancient times, and many papyrus records still survive.
