本文探討德國柏林國家圖書館之發展。該館在十七世紀的前身為選侯圖書 館，先後更名為皇家圖書館與普魯士國家圖書館；而在二次世界大戰後，分裂 為東柏林的德意志國家圖書館與西柏林的普魯士文化資產國家圖書館；雨德統 一促使該館重整為柏林國家圖書館。柏林國家圖書館的發展與德國政治歷史演 進息息相關，除做為普魯士文化繼承者外，現更為德國的跨區域綜合學術圖書 館，隨著兩德統一，其扮演的文化角色將更為重要。

This article scrutinizes the development of the Gennan Berlin State Libraiy. The institution was originally founded in the 17th century as Electoral Libraiy of Colin on the Spree? and has been renamed as Royal Library and as Prussian State Lihraiy. After World War II? it was divided into two separate libraries: German State Library in East Berliiij and State Library of the Prussian Cultural Foundation in West Berlin. The unifLcation of Germany helped to integrate the former Gennan State Library and the State Library ofthe Prussian Cultural Foundation into the Berlin State Library in 1992. The development of the Berlin State Libraiy is closely related to the evolution of German political history. Except acting as ail heir of Prussian culturej it is now a cross-regional comprehensive academic library. Coupled with German reunification， the Berlin State Library will assume a cultural role greater than ever.
