電子資源館藏與服務在目前的大學圖書館佔有重要地位，大量且廣泛使用的對象為教師與研究生。雖然電子資源受到使用者的喜愛，但是也帶來許多複雜問題，因此，有必要從使用者的角度針對大學圖書館電子資源進行服務品質評鑑研究，有助於圖書館管理者未來發展出更符合使用者期待的電子資源服務。本研究之研究目的包含以下幾點：(1)探討大學教師與研究生對於圖書館電子資源服務的認知、重要性及使用現況；(2)探討電子資源服務品質評鑑意涵及可評鑑項目；(3)建構電子資源服務品質評鑑指標與測量工具；(4)實施電子資源服務品質評鑑以改善其服務品質，進而提供最佳電子資源服務。 本研究透過焦點團體法具體建構出大學圖書館電子資源服務品質評鑑指標，共包含三個構面與28項指標，訪談結果亦作為發展問卷之基礎。為確保指標的可行性，研究者實際發放問卷予政治大學的教師與研究生，獲得以下結論：(1)網路使用時間會影響使用者使用圖書館電子資源的頻率；(2)使用者使用圖書館中文資料庫的使用率明顯高於西文資料庫；(3)使用者使用圖書館資料庫的主要目的為「學術研究」與「課業學習」；(4)「圖書館電子資源指南」與「圖書館學術資源探索系統」為使用者查找圖書館電子資源的主要管道；(5)使用者的圖書館資料庫檢索方式以「基本檢索」與「進階檢索」為主；(6)使用者偏好將電子期刊或電子書列印紙本閱讀；(7)使用者肯定圖書館電子資源對於「完成論文計畫書/論文」、「完成作業/報告」、「提升學術研究效益」的價值；(8)沒有圖書館資料庫推廣活動參與經驗的使用者高達六成；(9)使用者認為圖書館最重要的電子資源服務為電子資源的全文提供與權威性；(10)使用者認為圖書館最滿意的電子資源服務為電子資源的權威性；(11)使用者認為圖書館最不重要的電子資源服務為館員回應線上諮詢服務的速度、館員對於使用者電子資源需求的掌握；(12)使用者認為圖書館最需要改進的電子資源服務為電子資源的全文提供、電子資源網站取得全文的易用性；(13)整體滿意度尚待提升，政大圖書館應著重電子資源館藏的提供。 針對所獲得的研究結果，本研究提出幾點建議：(1)圖書館應深入了解教師及研究生的需求，充實電子資源館藏的數量與品質；(2)在電子資源網站上放置清楚的圖示或連結、提供完整的資料庫說明；(3)圖書館與資料庫廠商應定期舉辦使用者滿意度調查；(4)配合課程提供教師相關的資料庫清單與資料庫講習訊息、提前於暑假期間針對碩一生開設電子資源基本搜尋課程。 / Electronic resources collections and services occupy an important position in current university libraries, a large number of teachers and graduate students use them widely. Although electronic resources are popular with users, they also bring a lot of complex issues. Therefore, it is necessary to use point of views of users to conduct service quality evaluation for electronic resources in university libraries. It can help library managers to develop electronic resources services more in line with user expectations in the future. This research has four purposes: (1) to investigate the cognitive, the importance and current use of library electronic resources services for teachers and graduate students ; (2) to explore implications and availability of electronic resources service quality evaluation; (3) to construct indicators and measurement tools of electronic resources service quality evaluation; (4) to implement electronic resources service quality evaluation to improve service quality, then providing the better electronic resources services. This paper had formed focus groups to construct electronic resources service quality evaluation structure which is including three dimensions and 28 indicators. Interview results also use as a basis for the development of questionnaires. In order to ensure the feasibility of indicators, questionnaires have been collected from teachers and graduate students of National Chengchi University, and obtained the following conclusions: (1) Internet usage will influence the use frequency of library electronic resources; (2) the usage of Chinese databases significantly higher than the Western languages databases; (3) the main purpose of the library users to use databases are “academic research” and “learning”; (4) “E-Resource Gateway” and “Discovery Services System” are main channels of users to find the library electronic resources; (5) “Basic Search” and “Advanced Search” are main retrieval methods of library databases of users; (6) users prefer print out electronic journals or e-books to read; (7) users affirm Library electronic resources are good for the value of “complete proposal and thesis”, “finish homework and report”, and “enhance effectiveness of academic research”; (8) users who did not participate in promotional activities of library databases up to 60%; (9) users consider the most important electronic resources services are full text and authority of electronic resources; (10) users consider the most satisfying electronic resource services is authority of electronic resources; (11) users consider the least important electronic resources services are response speed of online consulting services of librarians and grasping of user requirements of electronic resources of librarians; (12 ) users consider provide full-text of electronic resources and the usability to get the full-text in electronic resource websites are electronic resources services that most need to improve; (13) overall satisfaction has yet to improve, National Chengchi University Library should focus on providing electronic resources collections. According to the research results, this paper also proposed several suggestions: (1) the library should understand the needs of teachers and graduate students, and enrich the quantity and quality of electronic resources collections; (2) the library should place a clear icon or link in electronic resource websites, to provide complete descriptions of databases; (3) the library and database vendors should conduct user satisfaction surveys regularly; (4) the library should provide teachers with related databases lists and databases workshops messages, and offer basic search courses of electronic resources during summer vacation for freshmen in master’s program.
