隨著電子圖書館系統的增多，想要從中找到一個最適合使用者使用的系統，其困難度勢必增加，因此了解與評估電子圖書館系統愈形重要。換言之，為使電子圖書館服務更符合使用者的需求，不論其硬體設備、收錄內容、提供之各項功能及介面設計上，都必須經過審慎地規劃、執行與評估，方能提高其使用效益與達成開發目標，以作為改進系統、提升資訊服務品質的依據。 本文以查詢過程記錄分析法評估臺大電子圖書館與博物館系統。除介紹查詢過程記錄分析法之基本概念外，另實際運用此方法於臺大電子圖書館與博物館系統之評估。最後，並提出本人對此系統之建議及未來之研究方向。

　　　　　The rapid growth of digital library systems makes it difficult for users to choose a suitable system, therefore it becomes more and more important to understand and evaluate digital library systems. In other words, the digital library systems must be carefully planned, implemented, and evaluated to fulfill user's requirements, no matter on its hardware equipments, contents, functional capabilities, and interface features. This article uses transaction log analysis to evaluate the Nation Taiwan University Digital Library and Museum (NTUDLM). In addition to describing the basic concepts of transaction log analysis, this article analyzes the application of transaction log analysis on NTUDLM. At the end of this article, the author also provides some suggestions for NTUDLM and future research of digital library systems.
