Kaufmann displayed a many-sided literary activity. The bibliography of his works, which M. Brann compiled for the
Gedenkbuch zur Erinnerung an David Kaufmann (ed. M. Brann and F. Rosenthal, Breslau, 1900), includes 546 items, covering nearly every branch of Jewish science. His voluminous contributions to the periodical literature of the last two decades of the 19th century show him as a finished writer both of German and of Hebrew. His first and most important works, dealing with the philosophy of religion, include: •

Berichte der Kaiserlichen Akademie der Wissenschaften, Vienna, 1874) •
