近年來，由於資訊科技的進步，圖書館中的電子資源數量快速增加，所佔預算金額比例也大幅增長。圖書館希望能夠透過評鑑電子資源的使用，以便能夠在電子資源館藏發展等方面做出正確的決策。由於體認到電子資源使用統計之重要性，圖書館界與相關組織紛紛發展或修訂圖書館統計標準，增列電子資源使用統計的項目以充分反映圖書館電子資源使用之狀況。本文主要採用文獻分析法以及內容分析法，收集探討並比較近年來國內外電子資源使用統計之相關規範及標準，包含ISO 2789、ICOLC Guidelines、ANSI/NISO Z39.7、CNS13151、ARL E-Metrics、E-Measures Project、以及Project COUNTER等。

Recently, due to the advances of information technology, electronic resources are gradually replacing print resources as the largest consumer of library acquisition budgets. Logically, libraries want to evaluate the usage of electronic resources and incorporate the results into their decision making regarding electronic resource acquisition. Over these years, there is a general awareness among libraries to develop statistics standards and guidelines for library electronic resources usage. In this paper, literature review and content analysis methods are used to compare several library statistics standards, including: ISO 2789, ICOLC Guidelines, ANSI/NISO Z39.7, CNS13151, ARL E-Metrics, E-Measures Project, and Project COUNTER etc.
