PhilPapers: Philosophical Research Online
Although officially a freely accessible resource, PhilPapers actively solicits subscriptions from institutions offering philosophy degrees in high-GDP countries. On-campus users from non-subscribing institutions encounter a pop-up notification and a brief delay when initially accessing the site. The continuously updated database now contains over 1.8 million citations to books, journal articles, reviews, dissertations, personal websites, open-access archives, and other philosophical literature in over 30 languages. Inclusion of notices of forthcoming publications makes it an excellent current-awareness tool.
