scholar.archive.org / fatcat
The Internet Archive's scholarly catalogue (fatcat), offering full-text search across more than 25 million open-access papers, including preservation copies of articles. You search it through the scholar.archive.org website. It is best reached via the web interface for now, since its lookup API was unreliable when last checked.
