Any In-Depth Middle East Posal Stationery Catalogs Out There?

Does anyone know of any specialty in-depth Postal Stationery catalog that covers the countries located in the Middle East region, or perhaps any individual country catalogs that do the same thing? I have a few that cover some of these countries, but they all see to end somewhere in middle of the period that I need to know anything about. Any ideas? Language not a problem, as long as they are fairly well illustrated, and cover all the little varieties. Thanks.

Higgins and Gage? The last ones to come out were around the 1980s so they would not have modern day stationery, though. Have you called the research librarians at the American Philatelic Society Library in State College, Pennsylvania? They might know of other reference books on the subject.
