"The News Archive Partner Program provides a way for Google and publishers and repositories to partner together and make historical newspaper archives discoverable online. As part of Google News, the News archive search function provides an easy way to search and explore historical archives. For articles already in digital format, we've worked with the hosts of these archives to crawl and index their materials. When materials aren't easily available in digital format, we have partnered with the copyright holder to scan and present the newspaper in a way that is full-text searchable, fast and easy to navigate," explains Google.
Google also digitizes books, magazines, photos and videos.
