This appears to be an authoritative source for information on the Persian Gulf region. (excerpt:)
"This site was developed by the Gulf/2000 Project at the School of International and Public Affairs of Columbia University in New York City. It is designed to make available in a single location a wealth of information on the eight countries of the Persian Gulf region--Bahrain, Iran, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates.
