A process or result of a gradual change from the original appearance of a material, such as paper, due to aging or environmental changes, or both. While yellowing in paper is especially pronounced in papers produced from mechanical wood pulps, it occurs to a greater or lesser degree in virtually all types of vegetable fibers. It is frequently associated with brittleness in paper (although not necessarily), and is sometimes referred to as "color reversion." (17 , 72 )
