As tribute, many of his fans and followers have begun posting links to research and academic papers, which are being collected by a new site. Swartz was a relentless proponent of open information; he fought repeatedly against JSTOR due to its tendency to charge the public for scholarly articles and pay the proceeds to publishers rather than authors.

At the time of writing, PDFTribute has over 1,500 collected links, ranging across all subjects. You can check them out here.
