圖書館為保存原件資料及提昇服務品質，逐漸將「珍貴」館藏予以數位 化，在進行數位化前，應考慮著作權問題、保存優先性、儲存媒體、索引及檢索 方式等項目，此外，本文將透過康乃爾大學的計劃，介紹「完整資訊擷取」的概 念與所需的程序，所謂「完整資訊擷取」是指希望在數位轉換的過程中，原件資 料的內容不會流失;另透過由英國伯明罕大學、牛津大學、里茲大學、曼徹斯特 大學所進行的ILEJ計劃，對數位化程序及其可能發生的問題加以探討。

　　　　　In order to preserve original data and to enhance the quality of service, library begins to conversevaluable collections into electronic form. Before doing this, there are several issues to be noticed first,such as: copyright of original data; what should be conversed first; what kind of storage media, indexsystem, and access methods to be used.. This article introduces two programs: the University ofCornell's program and the Internet Library of Early Journals ( ILEJ ) program. The program of University of Cornell brings the concept of "Full Information Capture ". Thatmeans the result of digital conversion should be exactly the same data as the original ones. The ILEJ program is the first stage of Electronic Libraries Programme ( eLib ) , organized byUniversity of Birmingham, University of Leeds, University of Manchester, and University of Oxford.
