Browning begins with the definition and origin of paper, giving a brief history. She describes the different materials of paper, concentrating on the chemistry of cellulose fibers. There is a detailed analysis on the prep-aration of chemical wood pulp, describing several different methods. She mentions the nonfibrous materials added to paper to give it the wide range of qualities it has. She also writes about the manufacture of paper. There are three measurable qualities of paper: physical, optical and chemical. The physical properties involve resistance to tearing, tensile strength, folding endurance, finish, smoothness, and absorption. Optical qualities include color, brightness, and opacity, the chemistry concerns composition. There is also a discussion on the stability of paper and the concepts of durability and permanence. She plots the rate constants for three aging papers and finds that in papers that change at the identical rate, the one with initial higher strength will always retain more strength, however a comparison with a paper with high original strength but a higher rate of strength loss will deteriorate most quickly. -- AATA
