Many efforts to understand the deterioration processes of the beeswax-treated volume of "The Annals of Joseon Dynasty" have been made. However, most previous studies have focused on individual sample sheet of the beeswax-treated paper but not book volume format. In this study, humid cycling accelerated aging for duplicated beeswax-treated book volume and Hanji book volume were carried out to examine differences in the deterioration of different parts of each volume as well as between the two book volumes during the aging. As results, it is found that the deterioration rate for the beeswax-treated volume is higher than that for the Hanji book volume. Different parts in each volume show different magnitude of deterioration. In particular, outer sides in both beeswax-treated and Hanji book volumes, which are directly exposed to the air, are deteriorated more seriously than inner sides. It is also observed that inner sides are considerably deteriorated during the aging, implying that inner deterioration may have different mechanisms from outer deterioration.
