PhilPapers: Philosophical Research Online

Rutgers Restricted Access

Off-campus users will be prompted to log in


PhilPapers has four components: an index, an open access archive of books and articles, a structured bibliography, and an archive of discussions, announcements, and jobs.  The index has roughly 20 million citations to books and articles, collected by trawling and by contributions from over 5000 individuals.  The archive of books and articles consists of some 20,000 papers and dissertations submitted by their authors.  The structured bibliography lists a half million citations in over 5000 topics, coordinated by hundreds of scholars in their fields.  The more than 100,000 registered users participate in online discussions in several hundred categories.    


Explanatory texts and FAQs are available on the site.

For help using these indexes see: How do I find an article on my topic?
