It is the successor to the Royal Historical Society Bibliography of British and Irish History, available online from 2002 to 2009.
Historical Abstracts covers the history of the world (excluding the United States and Canada) from 1450 to the present, including world history, military history, women’s history, history of education, and more.

A partnership of more than sixty major research institutions with Google, the Hathi Trust Digital Library includes all the book images from these libraries that have been digitized by Google. Only out-of-copyright images (generally pre-1923) can be displayed, or others where the permission of the copyright holder has been obtained, though both in-copyright and out-of-copyright materials can be searched. Out-of-copyright books can be downloaded by Northwestern users who register with the site.
