PCI is an electronic index to the contents of thousands of periodicals in the humanities and social sciences, from their first issues to 1995.
Every article is indexed.
Every year, it adds records for more than one million new articles. It will grow to encompass over 5,000 journals and 20 million individual articles. PCI is available to libraries and academic institutions on an annual subscription. Recently the scope of new journals has been extended to 1995, and existing journals will be updated in the near future. A full-image edition of PCI is now available.
