The Good, The Bad, and The Ugly
PhilPapers is a comprehensive index and bibliography of philosophy maintained by the community of philosophers. They monitor all sources of research content in philosophy, including journals, books, open access archives, and personal pages maintained by academics. We also host the largest open access archive in philosophy. Their index currently contains 2,713,240 entries categorized in 5,845 categories. PhilPapers has over 310,000 registered users.
The full text content of philosophy journals is not stored in a single repository. PhilPapers is the most comprehensive index for citations, but you will find the content of philosophy papers in JSTOR, Academic Search Complete, as well as publisher's repositories like Cambridge, SAGE, etc.
I recommend using PhilPapers to search for citations and Quick Search or Google Scholar to find the full text.
