Here are some titles you might want to check
out. With the exception of "From socialism to Islam" all of these
titles are available through ABE Books.
For that one I could not locate a local source. It is however
available through Ohiolink or UW Madison. If you are so inclined
you could probably score it through interlibrary loan from your public
library. I also located this Wikipedia web page that might be of
interest. http://en.wikipedia.org/wiki/Islam_as_a_political_movement. The Ejournal Socialism Today also has a lot to say about Islam and the Arab World.
