Bibliotheca Islamica (BI) is the Orient-Institut Beirut's platform for the critical edition of
mainly Arabic texts. The series dates back to 1929 when Hellmut Ritter edited the Kitab
Maqalat al-islamiyin wa- tilaf al-musallin of Abu l-Hasan Ali al-Asari a seminal text on
dogmatic positions in the early Islamic period. Since then the OIB has published more than
fifty titles in this series.
