The aim of this study is to estimate and compare indoor air quality(IAQ) at stock rooms in general library and in National Archives and to provide fundamental data in order to enact the law on management of IAQ at stock rooms in general library. The survey of IAQ in stock rooms was performed in Seoul National Archives in August 2009, and the basic data on level of indoor air pollutants in stock rooms at general library was collected from domestic journal. The concentration of NO2 was 114.1ppb at audiovisual documentary stock rooms in National Archives. That value exceeded 50ppb guideline that was legislated by the Korean Ministry of Public Administration and Security. The concentration of PM10 and VOCs were 59±9㎍/㎥ and 367±83㎍/㎥, respectively at stock rooms in general library. These values were exceeded from the guideline of Korean Ministry of Public Administration and Security that is 50㎍/㎥ for PM10 and 400㎍/㎥ for VOCs. Also, the exceeded probability from the guideline was 83.7% in PM10 and 35.6% in VOCs. Therefore, we suggest that a national plan for the management of IAQ at stock rooms in general library should be established. Keywords：Stock room, Library, National archives, Indoor air quality
