參訪--2005拜訪UCLA Archives



UCLA電影、電視資料館是唯一有媒體研究資源,而且是館藏量是全美國最多館藏之一,僅次於華盛頓國會圖書館。片庫則超過220,000影像和2億7千萬呎的新聞影片。




UCLA硝酸片館藏之處,消防設備相當全完,並且放置於一間一間的小房間內隔離,萬一若火災,才不會殃汲其他片庫。 硝酸片(Nitrate -Base Motion Picture)的特性就是具有易燃性、不穩定性以及高溶解性。 攝氏40度以上則會自燃, 最理想的保存溫度為攝氏4度 ,由於硝酸片材質上特有的化學質性, 使其有良好的物理韌性, 但卻有著相當低的化學穩定性, 故使其極易燃燒,故俗稱為“易燃片”。


館方接待人員示範硝酸片和醋酸片,同時著火時,硝酸片立刻燃燒的情況。
