數位時代網際網路盛行，受到民眾喜愛但也改變了對圖書館的使用習慣，OCLC 在2005年《圖書館與資訊資源看法》(Perceptions of Libraries and Information Resources)的報告中，調查讀者的資訊尋求行為和習慣，發現讀者使用網路搜尋引擎的頻率和滿意度等各方面評價遠高於圖書館資源。此調查結果帶給圖書館事業一大衝擊，反思是否讀者並不瞭解圖書館的價值？圖書館能提供什麼資源與服務？以及圖書館員的能力可提供什麼協助？ 因此本研究旨在從圖書館的核心價值探討圖書館存在目的、功能和服務目標，從價值延伸出圖書館員的職責和角色，為以背負及擔任這些的任務和角色，進一步探討圖書館員需要哪些專業能力範圍與指標。本論文主要參考美國圖書館學會2004年擬定圖書館的11項核心價值，以及2008年擬定的《圖書館事業核心能力》作為焦點團體訪談議題的參考，經過三場焦點團體訪談後，擬定《我國圖書館價值和館員基本專業能力清單草案》，然後將此草案藉由問卷調查進行項目確認。 本論文研究結果產出我國圖書館價值共12項、圖書館員角色11項、圖書館員基本專業能力共8大範圍55項指標、數位時代圖書館新業務功能14項。研究建議包括提供中華民國圖書館學會作為圖書館價值與館員專業能力宣示文件之參考、提供國內圖書資訊學系所訂定學生專業能力之參考、提供圖書館任用新進館員與評鑑現有館員標準參考、對中華民國圖書館學會館員教育訓練之建議、提供我國圖書資訊學教育規劃之參考、提供我國圖書館人力資源規劃的指南、提供我國圖書館員繼續教育課程規劃之參考。 / Internet became more and more popular in the digital age, but it also changed the habits of library use by people. In 2005, there was a report from OCLC, “Perceptions of Libraries and Information Resources”, which investigated users’ information-seeking behavior and habits ,and found that the frequency and satisfaction in using the Internet search engine by users was much higher than library resources. The result of this investigation made a great impact on the librarianship to reflect that maybe users don’t really understand the values of libraries, and what resources and services can libraries provide, and the competencies of librarians can offer any assistance? This study aims to explore the core values, purpose, functions and objectives of libraries, and then extends to research the roles and the core competencies of librarians. This study used two research methods ,which were focus groups and questionnaire survey. There were two main references to focus group, the first one was “Core Values of Librarianship” from ALA in 2004, and the second one was “Core Competencies of Librarianship ” from ALA in 2008. After three interviews with focus groups, drew up “Draft Statement of Library Values and Core Competencies in Taiwan”. And then the draft was confirmed by questionnaire survey. The research findings are as follows:(1)summed up twelve library values; (2) summed up eleven roles of librarians; (3)summed up a list of core competencies of librarians in Taiwan including eight categories and fifty-five indicators; (4) summed up fourteen new functions of libraries in digital ages. Based on the final results of this research, several suggestions are as follows: (1)to provide a reference document as “The Declaration of Library Values and Core Competencies of Librarians” for Library Association of the Republic of China(Taiwan); (2)to provide a reference document for the college department of Library and Information Science to draw up core competencies of students;(3) to provide a reference standard for libraries to evaluate new librarians and existing librarians;(4) to provide some suggestions of education and training courses for Library Association of the Republic of China(Taiwan);(5)to provide a reference plan of education and training for the college department of Library and Information Science;(6)to provide indicators to human resources plan for libraries;(7)to provide reference plans of continuing education courses for librarians.
