Search across many resources at once for NU library books, journals, documents, films/media and other library items as well as articles from select databases, digitized collections and more.

A partnership of approximately 140 research institutions with Google, the HathiTrust 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. For more information on searching Hathi, see http://libguides.northwestern.edu/hathi
