This natural process occurs when the paper is exposed to air and light, causing the fibers to break down and become more fragile. As a result, the pages gradually turn yellow. 2. Acidic Degradation Another key factor contributing to the yellowing of book pages is the presence of acids in the paper. Acidic compounds, such as lignin, are
