本研究之目的為：(一)探討大學圖書館館藏遺失損毀現況。(二)探討大學圖書館館藏資料安全防護措施與政策。(三)比較大學圖書館主管與館員及使用者對館藏安全看法與態度，並據以進行分析整理，以作為圖書館館藏安全措施與政策未來發展建議。 本研究以相關文獻為基礎，並採用深度訪談法做為研究工具，綜合研究結果與分析，整理研究結論如下： 一、因公德心低落，大學圖書館館藏遺失損毀問題以錯架、註記居多 二、期刊比其他館藏容易遺失，經費與驗收狀況需彈性處理 三、制訂讀者違規處理辦法，有助於減少館藏遺失損毀的發生 四、圖書安全系統目前仍是維護館藏安全最普遍設備 五、偷竊館藏行為目前仍無強硬措施 六、政策執行著重分層負責與溝通 七、圖書館使用者在意館藏遺失問題，希望多舉辦政策推廣活動 由研究結論歸納建議如下，期能供大學圖書館及未來之研究者做進一步研究之參考。 一、館藏安全管理層面 (一)圖書館需重視館藏遺失與損毀事前預防工作(二)加裝多層防護裝置(三)多元化的人力運用(四)善用科技減少人力成本(五)建立政策溝通管道。 二、行政執行層面： (一)成立館藏安全維護工作小組並制訂政策(二)訂定館藏安全工作手冊(三)政策修訂與時俱進(四)政策執行著重分層負責與溝通(五)期刊建議以經常門編列或以系統驗收(六)處理違規行為應以教育為目的(七)保留館藏安全事件完整紀錄(八)透過實質合作加強圖書館與其他單位之互動關係(九)運用社群媒體與推廣活動宣導政策與服務(十)推廣公德心教育與使用者建立良善互動。 / The purposes of this research are: 1) Study the current situation of collections loss and mutilation in University Libraries. 2) Study the collections security policy for University Libraries. 3) Analyze, collate and come up with suggestions for library collections security policy which are based on the comparison of the views and attitudes of University Librarians with users about the library security. On the basis of the relevant literature, we used in-depth interview as the experimental tool to draw the conclusions according to the analysis and results. The study gets results in six aspects: 1.Because low public morality, the majority problem of the collection lost, mutilation for the university library are wrong frames and notes. 2.Periodicals are less likely to be lost than other collections, so budgetary and acceptance methods need flexibility. 3.Formulating rules for readers' violation help to reduce library collection lost and mutilation. 4.Library Security System is still the most common equipment for maintaining library security. 5.There are still no tough measures to steal the collection and without any deterrent effect of punishment. 6.Library policy implementation should focus on stratified responsibility and good communication. 7.Library users care about the loss of the collection, and hope library to hold more policy promotion activities. The conclusion obtained from this research has led to the suggestions below that we hope to provide the University Library and later researchers a reference. 1.The Aspect of Collections Security Management 1) Library shall attach importance to the pre prevention work for the loss and mutilation of library collection. 2) Add an extra protective device for special collection. 3) Human resource utilization diversification. 4) Making good use of science and technology to reduce human cost. 5) Establishing a policy communication pipeline. 2.The Aspect of Administration and Execution 1) The library should set up the group for security maintenance working amd draw up a policy for collection security. 2) Set up the collection security handbook, 3) Revise the policy regularly to keep up with the times. 4) Policy implementation should emphasize that stratified librarians communicate and take responsibilities. 5) Periodical budget suggest for using current account fund, and check and accept by library OPAC, 6) Handling of irregularities should be used for the purpose of education, 7) Keep a complete record of the collection security events, 8) Strengthening the interaction between Library and other units through substantive cooperation, 9) promotion policies and services by social media and library promotion activities, 10) Promoting public moral education and establish the good interaction with library users.
