Specifying and managing light exposure for paper-based collections

The practice of restricting the exposure of light-sensitive works on paper to light, through a combination of measures, results from the historical, research-driven development of lighting guidelines. Currently, the lighting and presentation of such works employs risk-based guidelines and practices, led by nuanced considerations of the works’ longevity, value and significance, combined with scientific studies of their light sensitivity. Current lighting decisions will impact the works’ future condition and significance.
