Routledge Library Editions: International Islam [PDF ebook] 

First published between 1913 and 1994, this 6 volume set examines the history of Islam in a variety of regions across the world. Spanning continents from Africa, to Asia, North America and Europe, and ranging from 19th century ethnographical studies to modern day historical research, these titles not only demonstrate the diversity within this global religion, but also how the study of Islam has changed over time. The titles in this set will be of interest to those studying the history of Islam as well as those fascinated by the study of religion and international communities itself.
