A New Search Engine for Scholarly Works
Did you know you can now search for scholarly materials that are preserved in the Internet Archive? Introducing the Internet Archive Scholar, a search engine of 250 million research articles, from rare 18th-century field notes to conference presentations, or the latest preprint publication. Research shows that too often Open Access publishers just disappear, and with them go the links to troves of important scholarship. The Internet Archive Scholar seeks to preserve Open Access works and make it easier to discover them through full-text-search.
