Brockelmann’s Geschichte der arabischen Litteratur offers bio-bibliographic information about works written in Arabic and their authors, with an emphasis on the Classical Period. The multi-volume reference work is divided into chronologically-organized sections, subdivided by literary genre. Individual entries typically consist of a biographical section and a list of the author’s works in manuscript and print, with references to secondary literature. Brockelmann Online consists of both original volumes as well as the three supplement volumes, including the indexes. It is full-text searchable, making it much easier to consult for researchers and students.
