近年來，圖書館普遍遭遇到館舍空間不足的問題，更面臨了經費緊縮而期刊訂費 卻以驚人的漲幅年年高漲的巨大壓力，加上期刊的種數因學科分野漸細而不斷的增加，因此 ，如何以有限經費訂閱最佳之期刊，乃是圖書館最重要之課題。 本研究乃是以臺北榮總圖書館所訂閱之西文現行期刊為研究對象，針對本院各科部醫生進行 問卷調查， 並調查期刊館內使用率、 查核期刊之訂價及期刊在 Science Citation Index/Journal Citation Reports 內之排行名次等方式以分析期刊的價值， 進而利用量化 的資料來決定期刊之訂購與刪除。 本院圖書館根據此份研究結果，1999 年實際刪訂了西文 期刊 82 種，共節省經費約 2 萬元美金。 本研究所發展之「決策模式（ Decision Module ）」，可合理地評量期刊之價值以決定訂閱與否，藉此可以建立核心館藏，達到提升期刊館 藏品質之目標。故此決策模式及本研究結果之期刊總排名表都能作為其他醫學圖書館選訂期 刊時之參考。

　　　　　Budget shortages and significant annual increases in journal prices (10 ∼ 20 %) have caused a serious problem in decision-making in the selection and deselection of journal subscriptions in most medical libraries. Several methods for selection and deselection of journals are described in the literature, but no complete option suitable for this library (The Medical Library of Veterans General Hospital-Taipei) could be found. The evaluation criteria used for this study are as follow: frequency of journal use; inclusiveness in Index Medicus, Excerpta Medica; standard core journal lists; impact factor of SCI; local availability; annual cost...etc. The results of this study--the Journal Ranking List of this library and the "Decision Module"--are valuable tools that can allow this library, and other medical libraries, to systematically select the core journals and deselect the less useful journals, enabling them to add some more valuable new titles.
