Adequate Temperature and Humidity for Books and People in a Library

Taiwan is located in a subtropical zone where there is a lot of moisture during the rainy season or typhoons. In other words, for most of the year, warm and moist climate are two typical features of Taiwan’s environment. This kind of climatic conditions (warm temperature and high humidity) create a suitable environment for the growing of bacteria, germ, mold and insects. Besides destroying books, data files stored on electronic support and paper, it also has a serious impact on human health. The experimental and statistical analyses of the results of this study show that factors such as the total number of people in a library, library floor area, time of day and floor position within the building, have not been showing causality with the bacterial colony count (CFU/m3).
