國立臺灣圖書館，其前身為日據時期的臺灣總督府圖書館，營運迄今已屆滿百年。走過政權轉變，經歷多次的組織變革，直到今日仍然為臺灣眾多讀者提供服務，影響其發展的因素值得探討。本研究將以組織發展做為研究主軸，探討國立臺灣圖書館的百年歷史發展，希冀可以從中獲得其成功發展的原因。根據此研究動機，研究目的為：(1)探討從臺灣總督府圖書館到國立臺灣圖書館組織結構的百年歷史發展與重要事件；(2)歸納國立臺灣圖書館的價值以及影響其發展的重要因素；(3)探討從臺灣總督府圖書館到國立臺灣圖書館的歷史發展與重要事件；(4)探討組織發展對國立臺灣圖書館百年歷史之影響；(5)探討國立臺灣圖書館百年歷史發展中的館藏建設。 本研究透過歷史研究法，以組織發展為研究主軸，並以國立臺灣圖書館歷史發展中的五大組織變革，作為歷史發展階段的分段依據，透過史料蒐集分析，探討國立臺灣圖書館的百年歷史發展。另外使用訪談法，透過與館員、學者的訪談，瞭解國立臺灣圖書館的組織與館藏現況，以及國立臺灣圖書館百年歷史發展過程中的重大歷史事件。經過歷史研究法的史料分析與訪談結果分析，獲得以下幾點結論：(1)國立臺灣圖書館是代表臺灣研究的圖書館，各個階段的組織因從隸屬不同，而有不同的發展；(2)組織功能隨著歷史發展而有所差異，組織功能也受到組織規程或相關條例的規範；(3)國立臺灣圖書館發展過程中的重大歷史事件也影響了國立臺灣圖書館的歷史發展；(4)國立臺灣圖書館的組織與歷史發展，亦受到館長成就事蹟的影響而有所改變；(5)國立臺灣圖書館組織的變革與發展，同時也影響了國立臺灣圖書館的歷史發展；(6)不同時期的組織發展，會因為所屬機關的變化而改變；(7)組織定位與組織發展息息相關，國立臺灣圖書館的研究型圖書館功能受到質疑；(8)圖書館上級機關的政策，影響了國立臺灣圖書館之館藏發展政策的制定與發展；(9)館舍的有無，影響圖書館的歷史與館藏發展；(10)1945年之後的館藏目錄出版不如日據時期編製的完善；(11)臺灣學研究中心與資訊中心為任務編組，業務推展上有其困難之處。 針對以上所獲得之結論，本研究提出下列幾點建議：(1)在組織結構上，應建立臺灣圖書館學的相關研究單位；(2)在人員編制上，應編制臺灣圖書館學的相關研究人員；(3)館藏特色的建立上，應區別出與其他典藏單位的差異；(4)數位典藏系統中的資料並不完整，應盡量將資料建置完善；(5)相關史料典藏單位不同，使得資料取得不易，可建立統一的查詢平台或是合作典藏目錄；(6)針對館藏特色，出版館藏目錄等。 / National Taiwan Library, as Taiwan Governor’s Library in Japanese ruled period, has been operated for a century.
