圖書館館藏資料酸化與劣化的情形日趨嚴重，自1970年代中期美國國會圖書館著手研究以「DEZ 亞鉛脫酸法」進行大量館藏資料的脫酸處理，才能及時地保留住即將劣化為塵屑的人類知識記錄。歐美日等國由來已久均積極研究其防治之道，過去二十餘年來有關大量脫酸處理技街的研究成果與實際運作成效，為圖書館與檔案館在資料保存與維護方面帶來了極大的鼓舞。筆者過去一年多來自網際網路上蒐尋了許多這類主題的文獻，以下擬就圖書館館藏資料酸化劣化問題及其保存對策等方面作一綜合性的探討。全文共分為七個部分:即（一）前言；（二）紙張酸化與劣化問題；（三）館藏資料的劣化情形；（四）館藏資料的保存對策；（五）大量圖書資料脫酸技街的研發及其應用；（六）企業化經營大量圖書資料說酸處理服務；（七）結語。期能呼籲我國圖書館界與文化建設主管當局應及早重視這個課題，並速謀其因應對策，俾讓我們的後代子孫能繼續使用珍貴的印刷型式之人類知識記錄。

　　The problems of collection deterioration in libraries is very serious. A large proportion of books and documents in libraries become brittle due to paper deterioration. The major cause of book deterioration is acidic compounds generated . during the modern papermaking process. Library of Congress of the United States began to conduct a project of mass deacidification for collection adopting the Diethyl zinc (DEZ) system in mid-1970's. There are also another countries, including France, United Kingdom, Germany, Japan, etc. to do their best in studying the significant strategies for acidic collections during the past thirty years. Fortunately, there were a lot of research results in mass deacidification technology. And these useful research results stimulate the conservator's served in libraries and archives. The author intended to describe the state-of-the-art of the acidic paper, mass deacidification technology and significant strategies for collection deterioration. The paper can be divided into even parts, namely, (l)foreword; (2)the problems of the paper deterioration; (3)the status of the library collection deterioration in various countries; (4)the efforts of library materials conservation and preservation; (5)study on the mass deacidification technology for general publications in libraries and its application in reality; (6)providing a business-level of mass deacidification for general library collections; and (7)konc1usions. The author deeply hoped that the precious human-beings' •printed materials could be preserved for the next generations after mass deacidification of collections.
