One of the things that makes OpenSSR different is that its entire corpus of research is open and available to anyone. OpenSSR's corpus is an excellent resource for research on academia itself, and opening up research is a key part of our mission. To achieve this, we offer an API for programmatic access, and bulk downloads.
OpenSSR's corpus is available for bulk download. You can download either our article metadata database (author information, paper abstracts) or the full papers (as a large set of PDF files).
