Cambridge Archive Editions Online presents a wealth of historical reference materials which otherwise would remain unknown, difficult to access, or fragmentary. Considered collectively, this body of documents represents many thousands of original documents of the National Archives (UK) represented in facsimile, including numerous maps, on the national heritage and political development of many countries. The value and discoverability of this content is enhanced immeasurably through CAE’s document-level citations and rich indexing. For many years CAE has specialized in the history of the Middle East, Russia and the Balkans, the Caucasus, Southeast Asia, and China and the Far East. Now, through collaboration between Cambridge University Press and East View, these materials are made searchable and accessible as never before in e-book form.
