Working together with the generous support of Prince Alwaleed Bin Talal, the Harvard University Library's Open Collections Program has digitized hundreds of Islamic manuscripts, maps, and published texts from the institution's vast holdings. All told, the project currently includes over 145,000 pages dating from the 13th to the 20th centuries CE. The documents are from many regions, including Saudi Arabia and Central Asia, and the subjects covered here include rhetoric, logic, philosophy, calligraphy, medicine, and law. Visitors can search the entire site, and they may also make their way through sections such as "Published Materials", "Manuscripts", and "Maps". The "Maps" area is quite a find, and visitors can browse maps such as a rendering of the Turkish Empire in 1714 and one of Syria from 1853. Of course, most of the materials here are in languages other than English, but for scholars of the Islamic world, this collection is invaluable.
