館藏是圖書館的核心，根據使用者的需求進行館藏發展與管理一直是圖書館最重要的任務，要如何建立適當的館藏，端賴館藏政策的訂定及選書工作的進行。行政院新聞局於民國93年推動出版品分級制度，用意在於杜絕色情暴力等不良書刊戕害兒童及青少年，而公共圖書館服務的年齡層以兒童及青少年居多，在面對出版品分級制時，有必要建立好館藏選擇及管理的基本原則。本研究針對建立限制級出版品之館藏政策相關議題進行探討，以期使適當的讀者進行適當的閱讀，保障閱讀自由，充分發揮公共圖書館在日趨多元且變遷快速的資訊社會中的時代使命。

Collection is the core of a library. Developing and managing its collection on the basis of users’ need is always the most important mission of a library, and appropriate collection establishment relies on the constitution of collection policy and the progress of book selection. In 2004 the Government Information Office has brought into force the rating system of printed materials to put an end to unhealthy books involving in sex or violence that harm children and adolescents, who are the major users of public libraries. Therefore, it is necessary to establish the basic principles of collection development and management in face of the rating system of printed materials. The present research discusses the related issues of establishing collection policies on restricted publications, in order to have appropriate readers read appropriately, to protect reading freedom, and to do justice to public libraries that have contemporary vocations in the information society with growing diversity and rapid transitions.
