It would be a serious omission to limit this presentation on accelerated aging of paper exclusively to aging in the dark. Traditionally, most accelerated aging experiments have excluded the effect of light, probably because most library materials are not expected to see a significant exposure to light. However, with the possibility of inclusion of appreciable lignin content in permanent paper of the future, accelerated aging in the presence of light will undoubtedly be practiced more widely. For those of us who need to undertake light-aging experiments, a useful handbook/guide was published a few years ago by Robert Feller (Feller, 1990). This work includes an extensive methodology for such aging experiments, as well as the underlying theory and principles.
