While the libraries in Zweibrücken were almost completely destroyed by the war events of the 17th century, the library in Bischwiller of the Birkenfeld line remained, which was brought to the Zweibrücken residence in the 18th century. It was held by Charles I, Count Palatine of Zweibrücken-Birkenfeld (died 1600), Duke Wolfgang, Count Palatine of Zweibrücken's youngest son, and was continually expanded by his heirs. In his will, Count Palatine Karl made it his duty to his heirs to maintain and expand the library and stipulated that "the library be left with the County of Sponheim". In the 18th century, intellectual life flourished in Zweibrücken, book printing (the famous editions of the Bipont Editions were published here) and of course also the library. The head of the library at that time was the grammar school rector Georg Christian Crollius, a renowned scholar. Since the end of the 19th century, the Bipontina had been part of the humanistic . After its dissolution, it became an independent state institution in 1988, then integrated into a newly founded Rhineland-Palatinate State Library Centre in 2004. References
