Titltes that have been out of print for a long time, but are still important for libraries and scholars will become easily available to a wider audience.

In Knowledge Triumphant, Franz Rosenthal observes that the Islamic civilization is one that is essentially characterized by knowledge ('ilm), for "ilm is one of those concepts that have dominated Islam and given Muslim civilization its distinctive shape and complexion." With an introduction by Dimitri Gutas. FRANZ ROSENTHAL (1914-2003) was Sterling Professor of Arabicand Semitic Studies at Yale University until his retirement in 1985.
