本研究旨在從館員與讀者的角度，探究其對公共圖書館效能評量指標與面向的重 視情況。 本研究採用問卷調查方法，以臺北市立圖書館館員與試者為調查對象。主要調查 結果發現： （ 1 ）館員與訪者對傳統量化指標、館藏取得及館員效能的重視程度存在顯著 差異；（ 2 ）最不受館員與讀者重視的評量面向為公共關係與傳統量化指標；（ 3 ）讀者 的圖書館利用情況與其對部份評量面向的重視程度之間呈現正相關； （ 4 ）分析館員的五 項人口變項顯示，其中僅有年齡會影響館員對部份評量面向的重視程度； （ 5 ）分析讀者 的五項人口變項則顯示，讀者會因為性別、年齡、職業的不同，而對部份評量面向的重要性 有顯著差異看法； （ 6 ）館員與讀者對各評量面向的重視程度，不因所處圖書館的條件差 異而有不同。最後，根據研究發現對圖書館與館員提出建議。
